Shake, Rattle & Roll IV

Jodie Abesamis is a college student of Mr. Zerrudo's chemistry class who fell in love with him. While in their class, Mabu, Jodie's boyfriend, makes an invention and accidentally fires it towards their dean, Ms. Bautista. One night, Jodie is still in the computer room finishing her project with Mabu. While working, Mabu gets mad at Jodie after she got insulted by Mr. Zerrudo during class because of daydreaming.

One day, Jodie daydreams about marrying Mr. Zerrudo and then attacks her without getting any help from the guests. Gretch, Jodie's friend, wakes her up and tells her that they should go to Mr. Zerrudo's lab later in the day to tell their feelings for him. After this, Mabu asks for Jodie's forgiveness while Jodie accepts it and admits that she actually has feelings for Mr. Zerrudo.

In the afternoon, Gretch, with Jodie, goes to Mr. Zerrudo's lab and catches him making and drinking a potion. Gretch tries to seduce Mr. Zerrudo but the potion turns him into a monster. Mr. Zerrudo attacks Gretch and kills her. Jodie escapes and tries to tell Dean Bautista about what happened but she doesn't listen to her, thinking that it's just an excuse for her failing grade in Mr. Zerrudo's class. Mr. Zerrudo suddenly appears and tells Jodie to meet him in the lab at night to take a test for her failing grade.

That night, Jodie enters Mr. Zerrudo's lab and makes a potion to stop Mr. Zerrudo from attacking her. Jodie tries to escape but is cornered by Mr. Zerrudo. Mabu and Dean Bautista, who are still in the school to talk about giving Mabu remedial classes after failing, go to Mr. Zerrudo's lab and find Jodie getting attacked. Mr. Zerrudo catches them and decides to attack and kill Dean Bautista instead, letting Jodie and Mabu escape.

As Jodie and Mabu try to leave, they meet the janitor and Mr. Zerrudo tosses him to a door, dying on impact. While they escape, Mr. Zerrudo catches up to them and attacks Mabu. When Mr. Zerrudo leaves to find Jodie, Jodie helps Mabu stand up and leave, only to get cornered by a gate, separating them from Mr. Zerrudo. Mr. Zerrudo is able to bend the gate as Jodie and Mabu head back to the lab.

While inside, Mabu tries to make his invention again while Jodie barricades the door. Mr. Zerrudo breaks the door and attacks Jodie, only to be hit by Mabu's invention and is seemingly killed. As Jodie and Mabu begin celebrating, Mr. Zerrudo grasps Jodie's foot, but Mabu successfully kills him permanently.

A family of architect Rod Mallari is about to move to a new apartment house. As he and his wife argue over their things, their daughter Nikkie, snoops over their argument and is caught by her nanny Gi, and explains what Nikkie's parents are fighting over. Tising, another nanny, calls Nikkie so that they can go to the playground to say goodbye to her friends.

While Tising, Nikkie, and Juni, Nikkie's sibling, are at the playground, a dog named Cha-cha, disappears even if it was tied to a tree with a leash. Soon, Nikkie catches a monster taking Juni out of her crib and kidnaps her to its tree. When Nikkie tells Tising about what happened, Tising doesn't believe her and calls the barrio's captain, Capt. Salvi, and lieutenant, Lt. Damaso, instead. The parents, who treat Juni as their own child, attack Tising who is held responsible for the disappearance.

When Nikkie sees Tising getting mobbed, she tries to explain about seeing the monster kidnapping Juni, but no one believes her and still attacks Tising. Tising is instructed to go to prison to be interrogated. When everyone goes home, Nikkie goes back to the monster's tree to confront it but the monster throws a bone at her instead, causing her to leave.

At night, Nikkie tells Yaya Gi about what happened. Yaya Gi believes her and tells her that the monster is called a Witawit. The Witawit are creatures who live in trees they like and capture children when they are upset at people who cut trees they live in. It just happens that children are the ones that play near trees and that's why they are the ones that get captured.

While Nikkie is asleep, the Witawit enters the house and makes different noises, causing Nikkie to wake up. Nikkie encounters the Witawit while she tries to find Yaya Gi and screams. When she goes upstairs, Tising, getting desperate, appears with a knife and tells Nikkie that they should go to the mango tree to find Juni.

While at the apartment, Nikkie's father feels that something has happened and that they should go back to the house. In the playground, Tising orders Nikkie to climb the tree to find Juni and never go down unless she finds her. Nikkie, in the tree, finds her friends Shiela, Bambi, and Andrew trapped in cages with Juni. Her friends tell her that they are hostages because of the Witawit getting worried about his tree getting cut. They also tell her that it was Cha-cha's bone that the Witawit threw at her and that the Witawit can communicate with them through their minds without talking at all.

Bambi asks Nikkie to help them escape but the Witawit appears before they can leave the tree. While this was happening, Nikkie's parents arrive back home and the captain and lieutenant find Tising waiting at the mango tree. Tising, having no more patience left, decides to cut the Witawit's tree, hurting the Witawit as well. The Witawit, hurt, asks Nikkie's help to stop Tising from cutting the tree. Tising complies and Nikkie tells the Witawit that Tising and the others don't know anything about its problem and that it should return Nikkie and her friends back so that they can tell the problems on its behalf.

The Witawit and Nikkie reconcile and it brings back the children, with Tising, the captain, lieutenant, Yaya Gi, and Nikkie's parents seeing it all happen. After a few days, the Witawit's tree stays at the playground and Nikkie's family moves to their new apartment. Nikkie, worried that the tree might be cut when they leave, is told by Yaya Gi to promise not to let any tree get cut as long as she goes anywhere. Nikkie promises and the episode closes with a shot of the kids painting the tree's trunk.

Colorful ladies who live in the slum talk about a Manananggal who is attacking near their place. Near the place of the colorful ladies, there lives a family consisting of Astrude, Puri, and Teks, Puri's son. They also have neighbors, Adobe and his sons, who tell them about the Manananggal and warn them to be careful around her.

During the night, Adobe and his sons are attacked and killed by the Manananggal as Puri and her family watch from inside their house. After this, their house is attacked but they survive.

The next day at the barrio's hospital, Astrude asks Dr. Apol if she can sell her blood. Dr. Apol tells Astrude rejects her offer, so she decides to find a job near them. Puri and Teks are also there for Teks' check-ups.

Puri asks why Dr. Apol picked their barrio to give medical help since there's a Manananggal in the area, but Dr. Apol doesn't believe in these things. A nun named Mary John overhears their conversation and tells everyone near her that they shouldn't fear the creature because it isn't real and that they should only fear other people.

The people disagree and talk a lot until Aling Iya arrives and they suddenly stop talking. Aling Iya gives Dr. Apol a bag and she leaves. Monang, the owner of the ladies club who is also there, asks why the doctor is interacting with Aling Iya, since everyone thinks she is the Manananggal.

At night, Astrude arrives back home and tells Puri that she got a job as a rapper. After this, they enter their house. Teks looks outside and finds someone lurking around. Puri and Astrude decide to hunt the person, but they find the Manananggal stuck on an antenna instead, revealing that it was Sister Mary John all along. Teks, still following the figure, finds the Manananggal's lower half. Mary John suddenly is able to escape, allowing Puri and Astrude to realize that there's a bag full of clothes near them and that Teks is missing. Teks finds his way back home and is greeted with a crying Puri.

In the daytime, Teks finds a rundown warehouse and hears sounds of arguing. Suddenly, Mary John appears, having presumably eaten someone. At the hospital, Monang and a group of people go to Aling Iya's home to kill her. Dr. Apol rescues her and reveals that she just roams around the streets at night to give the poor their necessities and that she isn't the Mananananggal. During this, Mary John stands near Puri and Teks. Teks decides to attack her but is stopped by Puri before doing it further.

In the nighttime, Teks roams around the nightclub Astrude works in to look for ingredients to kill Sis. Mary John. He decides to take bottles of hot sauce but is caught by Astrude. Outside, Teks tells her about his suspicions on Mary John, so Astrude believes him. They head to the warehouse to attack her, but they catch her turning into a Manananggal instead.

They try to escape, but Astrude knocks down a piece of metal, making a sound, and gets chased by Mary John. Teks escapes, but Astrude is attacked. Puri, realizing Teks and Astrude are gone, is also in the warehouse, but is chased by Mary John as well. Mary John leaves and chases Teks, who was putting hot sauce on her lower half and disintegrates it. Teks manages to get inside a large construction tube, letting Puri stab Mary John in the back after trying to get him.

Mary John is able to escape and attack Puri but is squirted with hot sauce by Teks, killing and exploding her. Puri is able to find Astrude and the three of them reunite, but they hear another flight of wings. It turns out that Dr. Apol was a Manananggal as well and that he and Mary John were just pretending to help the townsfolk. Puri decides to distract Dr. Apol while Teks puts hot sauce on his lower half. Dr. Apol tries to attack Puri but is struck with hot sauce and is cornered, letting the sun disintegrate his upper half. Sunrise comes and Puri and Teks celebrate their success.
