Juan, an octogenarian widower, rejects his daughter Elisa's invitation to move in with her, but his inability to fend for himself forces him to give in and go with her. As it was an impulsive decision that he did not consult with anyone about, Elisa will encounter a variety of opinions from the rest of her family.
