Jack and Jill (1954)

Siblings Benita and Gorio play twisted roles: she drives a jeepney, he does all the household chores; she gets into brawls with men, he prefers to be called "Glory." All these they do in support of their father, Mang Ambo, a driver for the rich and reckless Gardo, son of the elite Don Quinito and Doña Teresita. When Mang Ambo's health fails him, he introduces Benita to the family, disguised as a boy named Itoy. Gorio, on the other hand, runs away to look for a job and ends up being taken in and mistaken for an actual girl by Doña Teresita as her own "daughter." Living in totally new circumstances and with each bearing the secret of the other, how long can they keep up playing their game?
