Bernie (Jack Blake Jack Black) is an undertaker in Carthage, Texas. He is a professional, kind, generous, public-spirited, leading singer in church and performing in a community troupe, winning the hearts of everyone in the town, but he remains single and is suspected of either fawning on celibacy or being gay. After the death of a wealthy businessman in the town, Marjorie, an old widow who is eccentric and hated by everyone, is left behind (Shirley MacLean Shirley MacLaine). In line with the principle of "the most sincere sympathy and goodwill to each family", Bernie enthusiastically approached Marjorie and soon won her favor. She paid for all the fun expenses of the two, let Bernie participate in her property management, and even changed his will. Over the past two years, Bernie, whom everyone loves, has almost become the private property of Marjorie. She has dismissed all her employees and left Bernie with all the chores in her life. The good-tempered Bernie also broke out one day, and put an end to Marjorie's life in one step, acting in a play of "Marjorie had a Stroke". Bernie held on to the secret and tried to escape the law.... This film is based on a true story that happened in Texas.
