El cielo y tu (1971)

Father Mauro, a Catholic priest and social worker whose main goals are fighting against drug use and juvenile delinquency, is attacked by the servant of a wealthy man who has just given the priest an important amount of money to spend in his labors, and left for dead. He is found by the members of a hippie commune, who rescue him, but when he wakes up he can't remember who he is. He is taken for a gangster by the hippies, who offer him to stay with them, which he does. Mauro falls for Susana, a young girl who has joined the commune after the shock of seeing her father cheating on her mother with another woman. They eventually realize how crooked and wrong the hippie life is, and Susana starts to recover her faith in God. After she gets pregnant, the couple leave the commune, and, upon entering a church, Mauro remembers his identity. Now he'll have to choose between priesthood or the woman he loves and his son.
