Beyond Obsession (1994)

John Thompson strangles Eleanor DiCarlo, the unbearably manipulative, overbearing mother of his lover Traci, in her bedroom. Trough his and other people's testimony to lawyers, police, and in court and elaborate flashbacks, he comes to understand that Traci set him up no less wickedly and sacrifices him without hesitation. John is condemned to 34 years for the murder. A year later, his sentence is halved in exchange for being crown witness in her trial, where lawyer Jake Meletti does a brilliant job overemphasizing Eleanor's wickedness.
