Buried Alive (1990)

Clint Goodman is a successful contractor who built his comfortable house and his construction company in his hometown through hard work. He loves his wife Joanna, but she is resentful of him most of the time; the couple has been trying unsuccessfully to have a baby. Clint’s best friend is Sheriff Sam Eberly. Every now and then, they spend the night fishing on the lake. Unknown to Clint, Joanna has been having an affair with local doctor Cortland van Owen. He plans to kill Clint and have Joanna sell his company and house. With the money, they will move to Beverly Hills to buy a clinic. Cortland gives poison to Joanna, taken from a poisonous tropical fish.

Though hesitant at first, Joanna goes along with the idea. While having dinner with Clint, she begins to have a change of heart and starts pouring the poison away at the kitchen sink, but stops herself. She spikes his wine with the poison, but is startled by Clint and drops the vial with a small amount of the liquid left In It. After drinking the poisoned wine, Clint has a heart attack and apparently dies. When the coroner asks if an autopsy should be done, Cortland refuses. While Clint’s body is at the morgue, he shows signs of life. Just before he is to be embalmed, Joanna instructs that he be given a quick and cheap funeral instead, skipping the embalming process. Clint is placed in a cheap water-damaged casket, varnished to look like new. After his funeral, Joanna and Cortland celebrate.
