Mine Alone

An argument between a man and a woman is heard, then seen in black-and-white; then a series of flashbacks shows them meeting, getting married, and starting their family. The man is Joaquin, an ad executive with a fierce temper; the woman is Angela, a receptionist when they meet. The relationship unravels as each incident is more damaging. Angela's friend and confidante is the wife of Joaquin's boss, so their problems spill into his work. He refuses to seek help, and as he gets more threatening, the law does little. Is one or the other's death the only way this can end? And the flashbacks, where do they originate?
