Cain and Abel (Filipino: Cain at Abel) is a 1982 Philippine action thriller drama film directed by Lino Brocka from a written story and screenplay by Ricardo "Ricky" Lee.

However, the sibling rivalry became violent and bloody due to the issue of inheritance of their family land and Senyora Pina's favoritism to her younger son. It also stars Carmi Martin as Zita, Ellis's fiancée from Manila; Cecille Castillo as Rina, the house helper, and Ellis's other woman; and Baby Delgado as Becky, Lorenzo's wife.

Cain at Abel was released on October 8, 1982, by Cine Suerte Inc., it served as the first Filipino film entry for the San Sebastián International Film Festival in Spain in the same year, and received accolades from award-giving bodies for cinema.

Lorenzo, the eldest son of Donya Pina, returns home tipsy from a drinking party in the countryside and starts asking his mother about the idea of buying tractors for the farm. However, his mother refuses, citing that the farmers of the plantation would slack off. The conversation between Lorens and his mother turned into an argument after the former gave a threat to her. On the following day, Ellis, the youngest son, returns home from his studies in Manila and brought his classmate Zita, who will spend her vacation at the household. Later, while Ellis entertains his family, Lorens returned and sees his brother suspiciously due to his envy towards him and his mother's favoritism toward Ellis.

At dinnertime, Ellis began to notice why his room was used and Lorens replied that he used it for his sons. The questioning caused a small argument between the two brothers but their mother stopped it. A few hours later, Lorens went to the nightclub and they conversed with his friends, talking about his brother Ellis and Senyora Pina. While Senyora Pina mentioned her planned will and testament, Ellis wants the land to be his, and according to the matriarch, Lorens brought problems to the family, citing his mismanagement of the family plantation. As they continue talking, Ellis told to his mother that he decided to drop out of college and wanted to marry Zita. Senyora Pina, however, agreed with Ellis's requests, despite the criticism about Zita.

Ricky Lee (pictured in 2018) served as writer of the film.
