Dead in the Water (1991)

Prominent lawyer Charlie Deegan has almost everything he has ever wanted. He has an important, prosperous law practice, a beautiful secretary as his lover, and the chance to be appointed to the high court. The only thing wrong with this is that his shrewish wife Olivia, whose father made all the wealth and all the power, is living and berating him at every opportunity and that greatly upsets Charlie. So when his lover, Laura, jokingly suggests that they get rid of Olivia, Charlie thinks, being a successful lawyer, that he can actually create a fool-proof plan. In this plan, he must incorporate a socialite named Victoria whom he detests, but she can help him get into the court and be part of the plan for Olivia. But dreams of judgeship, money and Laura makes him proceed. However, things never turn out as planned and he may not be as smart as he considers himself.
