Salvadore Ross is a brash, insensitive, ambitious 26-year-old man who desires a lovely young social worker named Leah Maitland. Leah and Ross dated for a time, but she broke off the relationship because their personalities are incompatible. When Ross continues to bother her, Leah puts her foot down and finally ends things. He has been so loud that her father has come out to see if she is all right. After a curt exchange, they go inside and Ross slams his fist into the closed door, breaking his hand. This sends him to a local hospital, where he is forced to spend the evening. Ross' roommate is an elderly man with a respiratory infection. Ross sarcastically suggests that he would like to trade ailments with the old man, who jokingly accepts the trade and they go to sleep. Salvadore turns over quickly and hits his hand. He then realizes it no longer hurts and begins to unwrap it. As he unwraps it, he begins to cough. He gets out of the bed and checks the other man, whose hand has begun to hurt. The old man begs Ross to reverse this (at his age, the hand wouldn't heal properly), but Ross dismisses him.




Ross realizes he has a supernatural power to make trades with other people. In exchange for $1,000,000 and a penthouse apartment, Ross sells his youth to an elderly millionaire. As a result Ross is now very rich, but old. He offers a number of young men (beginning with a hotel bellboy) $1,000 for each year of their lives they trade to him. In short order, Ross is 26 again.




Ross is now young, rich, and (thanks to a trade with a college student) well-spoken, so he goes to Leah's apartment. Her father is there and unimpressed with the superficial change in Ross, knowing that he does not love Leah, but simply wishes to possess her. Leah comes home and, after she sees Salvadore has changed his ways some, agrees to go to dinner with him. However, by the end of the date she is again repulsed by Ross's personality. She wants a man who is as caring and compassionate as her father. Frustrated, Ross approaches Mr. Maitland, who is kind to him despite his disrespectful and condescending demeanor, but does not think he would be a good husband for his daughter. Ross offers him $100,000 to make him and Leah financially secure in exchange for something from Mr. Maitland. When the father asks what he has, Ross says, "Well, it's a little hard to explain..."




The next day, Ross has become warm, compassionate and has won Leah's heart. Ross meets with Mr. Maitland in private to apologize for his previous behavior and asks for his permission to marry Leah. Maitland refuses. Ross implores the older man to show compassion. Maitland coldly replies, "Compassion? Don't you remember? I sold that to you yesterday", and shoots Ross dead.
