Sam Stone

"Her father was very, very rich, and very, very sick. The doctors assured me he'd be dead any minute. There wasn't a second to lose! I rushed right out and married the boss's daughter. He was so sick, it was like the Angel of Death was sitting in the room with him, watching the clock. They pulled the plug on him... he wheezed and shook for about an hour... and then... he stabilized. The son-of-a-bitch just got older and sicker. And older, and sicker, and older and sicker...! I couldn't wait any longer, so I went out and made my own fortune. The old fart hung in there for 15 years. Finally died of natural causes. I want the rest of that money! His money, her money, it's my money!"

History
Sam Stone was once, presumably, a low-level employee in a multi-million dollar company who saw an opportunity to get rich by marrying his boss's abrasive daughter Barbara after the former became deathly ill. Sam disliked Barbara intensely and plotted to get rid of her to gain her fortune, but despite his illness, his father-in-law stabilized and managed to stay alive (but hospitalized) for fifteen years before finally passing away, forcing Sam to endure an unhappy marriage. During this time, he cheated Ken and Sandra Kessler out of their life savings to market a fashion design he plagiarized from Sandra, making a small fortune of his own as a result and leaving them in poverty. He also began an affair with a beautiful woman named Carol, who only put up with him because of his wealth.

Sam finally concocted a plan to kill his wife by knocking her out with chloroform and then tossing her off a cliff, but after explaining his plan to Carol, he could not find Barbara upon arriving home. He becomes angry and chases Barbara's pet dog, Muffy (whom he shares a mutual antipathy with), tossing the bottle of chloroform after her. He then receives a phone call, and a mysterious caller announces that Barbara has been kidnapped and will be killed unless Sam pays a ransom and does not alert the police or the media. Delighted, Sam quickly disobeys the caller's orders, and the police begin a city-wide search for Barbara, whose abduction becomes a top news story.

The kidnappers turn out to be the Kesslers, who want revenge against Sam for ruining their lives. Unfortunately, Barbara proves to be a handful for the kidnappers. Sam consistently refuses to pay the ransom and openly mocks the kidnappers when they try to lower it. He also makes more provocative moves on Carol, who is secretly planning to blackmail Sam with the help of her moronic boyfriend, Earl, neither of them believing that Barbara was kidnapped. At the supposed drop site, Earl tapes a prostitute and her john having wild sex, mistakenly believing that Sam is actually murdering Barbara.

Without watching the tape herself, Carol anonymously sends a copy to Sam, who quickly figures out who sent it and thinks that Carol sent it to him as a tittilating birthday present. He calls her and hits on her by saying he is going to do to her what happened in the video, but she misinterprets this as a death threat and sends a copy of the tape to the Police Chief Benton--who turns out to be the john in the video. She calls him and demands that Sam be arrested for killing Barbara. Thinking that he is being blackmailed, a confused Benton complies and orders a search of Sam's mansion, planning to plant evidence in it, but gets the shock of his life when real evidence is discovered: the bottle of chloroform (with Sam's fingerprints still on it) and photos of Sam with Carol.The kidnapping investigation, which has led straight to Ken himself by now, is immediately called off and Sam is arrested.

Meanwhile, a bored Barbara takes up exercise in the basement where the Kesslers are keeping her and loses a lot of weight, which delights her when Sandra tells her this. Sandra presents Barbara with several of her fashion ideas, and Barbara enthusiastically promises to advertise them world-wide. In her euphoria, Sandra lets Barbara go, but Barbara quickly returns when she finds a newspaper article revealing that Sam wanted her dead and had a mistress. She arrives just in time to see a serial killer attack the Kesslers, but he falls down the basement stairs and dies.

The trio plot revenge against Sam, who has just made bail and now faces the unhappy prospect of having to get his wife back in order to prove his innocence. When Ken calls Sam again, a relieved Sam agrees to pay the ransom, but armed with information from Barbara, they have increased the ransom to Sam's total net worth: $2.2 million. Sam is outraged, but has no choice but to comply. Meanwhile, Carol finally sees the tape and realizes Earl's mistake. Sam begs the police to come to the ransom drop site, but they refuse, thinking that the kidnapping was a hoax. Ken arrives in disguise at the drop site and takes the briefcase full of cash. Earl arrives and tries to take it, but the police (who have arrived en mass) capture him and allow Ken to leave despite Sam's protests. In the confusion, Ken drives off the docks and into the sea.

The police salvage a corpse from the water and find it is the serial killer from earlier. Sam thinks that Barbara will surely be killed at that her money is finally his, despite losing all of his own money, but then Barbara emerges from a police car. She identifies the serial killer as her kidnapper, claiming that he was schizophrenic and believed he had accomplices when he was really working alone. The police believe her and walk away in satisfaction while Barbara confronts Sam, who is taken aback by how beautiful she has become. However, she gives him a severe thrashing before throwing him into the water and walking away triumphantly. Some distance away, Ken emerges from the water in scuba gear with the briefcase in hand. He reunites with Sandra and Barbara, and they dance together.
