"A Part of Me" is a touching story about paternal love and sacrifice, where Ricardo, a devoted father of three, loses his wife to a heart disease and finds himself caring for his children and learning how to be an only parent. As time goes by, and he is getting accustomed to his new life, despite episodes where he daydreams about his deceased wife, he finds out that her heart condition is a genetic disorder when his eight-year-old son collapses in a park while playing tag and is taken into the emergency room. Ricardo makes a drastic and deeply moving decision, making the ultimate sacrifice to save his son so that he doesn't have to die the same way his mother did.
