WEEKEND AT BERNIE'S II

Larry Wilson and Richard Parker are at a Manhattan morgue where they see the corpse of their CEO, Bernie Lomax. Larry falsely claims Bernie as his uncle so he can get some of Bernie's possessions, including Bernie's credit card. At the insurance company, Larry and Richard are quizzed by their boss and Arthur Hummel, the company's internal investigator, who ask them if they have the $2 million that Bernie embezzled. They deny knowing where the money is, but their boss believes they are lying and fires them. He also sends Hummel after them, giving him two weeks to prove their guilt.

Over dinner, paid for with Bernie's credit card, Larry tells Richard he found a key to a safe deposit box in St. Thomas, U.S. Virgin Islands. Larry asks Richard if he will use the computer at work to see if the $2 million is in Bernie's account. At first, Richard refuses but ultimately gives in.

Meanwhile, in the U.S. Virgin Islands, a voodoo queen named Mobu is hired by mobsters to find the $2 million Bernie stole. She sends two servants, Henry and Charles, to go to New York, get Bernie's body, use a voodoo ceremony to reanimate him, and bring him back to her so he can lead her to the money. Accidents plague their attempts to get Bernie back. They prepare in a bathroom at a shady adult movie theatre for the voodoo ceremony. Having lost the sacrificial chicken, they use a pigeon instead. As a result, Bernie is reanimated but only moves when he hears music. At the 42nd Street–Grand Central subway station, Henry and Charles soon abandon him to chase a man who stole their boombox.

Later that night, Larry and Richard sneak into their office building to check Bernie's account, only to find that Bernie is the only one who can open it. Police officers soon arrest them for breaking and entering. After their release, they find Bernie, whom they believe is still wholly dead, stuff him into a suitcase, bring him with them to the Virgin Islands, and put him into a small refrigerator in their hotel room.

Unbeknownst to the two, Hummel is following them to recover the embezzled cash. The men use Bernie to open his safety deposit box, but only find a map. Meanwhile, Larry befriends a lovely native girl named Claudia and gives her the map. Henry and Charles capture the two and take them to Mobu. With one of the mobsters holding a gun to his head, she forces Richard to drink a poisonous potion and tells them they must find the map by sundown to get the antidote.

When Larry, Richard and Claudia are reunited, they are shocked to discover that the undead Bernie is moving and realize he is leading them towards the $2 million. They put a Walkman with headphones on his head to keep him moving. As Bernie finds a large chest underwater, their resulting excitement causes Larry to accidentally shoot Bernie in the head with a speargun, destroying the headphones.

They attempt to bring Bernie back to the surface but he will not let go of the chest, which is too heavy to hoist out of the water. They end up attaching Bernie to a horse carriage with music playing. It seems to work at first, but the carriage goes out of control when they go downhill. Eventually, the carriage ends up at Mobu's place. Bernie hits a large tree branch and spins into a somersault before knocking out Mobu. The crash also causes Bernie to drop the chest on the ground, and it breaks open. Larry tries to scoop up the money, but is caught by Hummel (now slightly unhinged upon seeing the undead Bernie walk), and he gives the $2 million to him. With Mobu out of commission, Claudia's father, a medical doctor, says that he can cure Richard if he can get the blood of a virgin (which Larry confesses he can provide). The mobsters and Mobu are arrested.

Larry confesses to Richard that he returned the $2 million to the insurance company, but only after learning Bernie stole $3 million. Larry and Richard use some of the remaining million to purchase a yacht crewed by attractive women. Bernie leads Henry and Charles, who have been transformed into goats by voodoo, through a Carnival parade.

Larry, Richard, and Claudia use Bernie's music-driven movements to locate a large underwater chest, following the clues to the embezzled fortune.

The ending wraps up the madcap chase with Larry and Richard finally leveraging Bernie's supernatural predicament to reach their goal. The film lands on a note of absurd triumph, reinforcing its commitment to farce: even in death (and with a little help from voodoo), Bernie remains the key to the duo's misadventure. The central conceit—using a reanimated corpse for personal gain—reaches its ultimate payoff, capping the oddball fantasy-comedy blend.
