Loving to death is centered on the lives of three men who die the same day: Leon Carvajal a business magnate is sent to kill for his wife and lover (Alejandro Nones) to be able to keep his fortune. Macario Valdés is a hired murderer imprisoned in a United States prison of which he is sentenced to death. Beltran Camacho is an anthropology teacher who dies in an accident on the road when he loses control of his truck and turns to a river. These men die the same day and their souls are reincarnated in different bodies. The soul of the entrepreneur will relive in the body of the killer who was executed in an electric chair, and for his part, the soul of the killer will reborn in the body of the anthropology teacher.
