[1] Produced by Regal Entertainment, it was released on December 25, 2005 as an entry to the 2005 Metro Manila Film Festival.

Chona, a pure Chinese, is his legal wife and the mother of their three children, Hamilton who is a closeted homosexual, and his daughters Hibiscus, and Anthurium.

At an event attended by the whole family, including Patty's, the two wives are startled when they see Elton arrive with his new mistress Gloria, a younger and more voluptuous woman and a pure Filipino.

While this plays on, Elton arranges for Hamilton, his legitimate heir, to be married to another Chinese-Filipino woman, Trixia.

Sometime later, Chona and Patty maintain their rivalry but are now on friendlier terms, while Elton accepts Hamilton's homosexuality as well as Nixon and Tricia's relationship.

As they watch their children perform in a band, Chona, Patty and Elton meet again with Gloria and her new romantic partner, an African-American.
