Ang Tanging Ina

Ina has four children with each of her three husbands: Tony (who dies after falling from a stool), Alfredo (who dies after falling in a cinema), and Kiko (who is electrocuted at their wedding reception). After Kiko's death, Ina decides not to remarry.

Ina wakes up to find her twelve children: Juan, Tudis, Tri, Por, Pip, Six, Seven, Cate, Shammy, Ten-Ten, Connie and Sweet facing various problems. She then discovers her family is in deep financial trouble and takes on multiple jobs, from construction to selling bootleg DVDs, to support them.

Ina is reminded of her debut by Por, and allows Juan to find work. Juan's chores at home confuse Ina. Her ex-driver, Bruno, suggests she work at a strip club for money. Juan encounters his ex-girlfriend Jenny at an amusement park and applies for a job there. Tudis quits her job to become an artist, and Tri tries to impress his girlfriend's parents with his intelligence. Por tries to get her crush, Jeffrey, to escort her to her debut. Pip, a closeted homosexual spies on his crush, Nhel. Six invites their mother to a retreat, and Seven leads a school program about mothers. Shammy tries to hide that he is uncircumcised, but Pip accidentally reveals this to Nhel, causing Shammy to hate him.

Ina's attempts to help her children backfire: she prevents Juan from marrying Jenny, Tudis refuses to help her find work, she reveals her stripping job to Tri and his girlfriend's family (causing their breakup), she fails to provide Por's lavish debut, and she disrupts Six's “church retreat” after mistaking it for a “trick or treat,” also learning that Pip is gay. Seven has not told Ina about the school program, fearing further embarrassment. Cate reveals Ten-Ten is deaf, and Shammy becomes ill after a botched circumcision. Ten-Ten then goes missing. Ina, still in her stripper outfit, rushes to the hospital to be with Shammy, causing her taxi driver, Eddie, to fall in love with her.  

During a family meeting, Ina's emotional explanation for taking on multiple jobs backfires, leading Juan to run away with Jenny. Rowena comforts Ina, who now worries about how to fix everything. After quitting her stripping job, Ina notices a suicide bomber on her bus. She alerts the other passengers and helps them evacuate before fighting the bomber. She escapes the bus just before the bomb detonates, killing only the bomber and leaving her with minor injuries. When news of the bus bombing reaches her family, they mourn a covered body in the hospital, believing it's Ina. However, she appears unharmed. She then resolves her family's problems: allowing Juan to date (but not marry) Jenny, convincing Tudis to return to work and Gretchen to reunite with Tri, accepting Pip's sexuality, being forgiven by Six, allowing Seven to complete her program, forgiving Shammy (who recovers), and finding the deaf Ten-Ten at a church.

At Por's smaller debut party, Eddie is launched into the air by a firecracker in his pocket. Ina reveals he survived and married her, but the incident left him unable to have children. The end credits show the family learning sign language to communicate with Ten-Ten.
