My Best Friend's Funeral

Jake was Cheryl's best friend. They were super close during high school but drifted apart after Cheryl's 18th birthday bash. She is 21 now and is attending his funeral . Turns out he left a will and that is what he was killed for. She is determined to find that will and find out who his killer is but when you are in Jake Welling's house you have many other things to worry about. Like, how to dodge his uncle who keeps hitting on you, his mother who doesn't like her dress, his sister who prefers wearing a bikini than an all black gown, his brother who believes Jake is going to rise from the dead and is busy taking drugs, his grandpa's photo which is all over the house, his basement which is a place for mourners to get drunk and his room which is spic and span. Jake never kept his room spic and span. Something is wrong. The coffin is left closed and Cheryl thought she saw Jake walk past his brother who was crying and laughing at the same time.
Now Cheryl wonders if he is really dead or not?
