Angelina is a seven-year-old brilliant and talented girl, but with an undeniably spoiled personality. After her first
yaya (
nanny) gets hospitalized due to a
fire started by Angelina while the nanny teaches her how to
grill, her parents decide to find her another
yaya who would control her behavior, and a lot of applicants quit the job due to Angelina's attitude. Rosalinda “Chacha” Lucero applies for the job, and is accepted. She assumes the job of looking after Angelina as an easy task, to which the latter proves otherwise. Shortly thereafter, some Incidents occur: • putting a can of
beer in a
microwave oven and causing an
explosion at a
supermarket, • fighting with her classmate in a
zoo, and • going up to a
belltower to disrupt the
wedding that her family attends. Angelina's mom decides to fire Chacha if she causes any more problems. Chacha is frustrated upon learning this, to which Angelina tries to make her happy, only to get her fired after accidentally killing her father's pet
fish. As her parents conclude a nanny cannot help their
daughter, Angelina lives momentarily without one. With no one to protect her, Angelina is accidentally
kidnapped by a group of
terrorists after overhearing their plan to
murder the
Duchess of Wellington, who is visiting Angelina's school. After receiving no response from her busy parents, Angelina calls Chacha. Angelina describes a place near a
warehouse, seeing the words LOSER, which is part of a sign which reads
Mano-LO SER-vice Center. Doubting Angelina's words, Chacha discharges her call. Later on, Chacha is convinced to help Angelina in order to prove the latter's sincerity. She goes to a
church, where she remembers the
bell ringing while Angelina was calling. There she sees the word LOSER and realizes that it is what Angelina exactly described. She realizes at once that the terrorists' hideout is near. At the warehouse, she finds Angelina and saves her. Meanwhile, Angelina's parents assume that Chacha kidnapped Angelina as revenge for firing her, which is eventually negated. After Angelina’s escape, the terrorists' leader, Eve, kidnaps her parents and holds them unless Angelinas gives a
bomb hidden in a
flower bouquet to the Duchess of Wellington as she makes her
speech. Chacha manages to avert the incoming crisis by switching it with another bouquet. Upon getting the bomb-ridden bouquet, Chacha enters Eve's bus and starts a
cat fight with her. Seeing that her plan has been foiled, Eve takes Angelina captive. Chacha tracks them down until she reaches the rooftop. She engages Eve once again to a catfight, but as the two women fight each other, the
billboard behind them crashes down, trampling Eve but miraculously leaves Chacha and Angelina unscathed. Angelina's
parents decide to reinstate Chacha as her permanent
nanny. The
Duchess finishes her speech and awards Angelina and Chacha for their bravery. Near the end of the film, Chacha's backside is written with the word "LOSER", and Angelina's is drawn with
wings. ==Cast and characters==
