Sibling Rivalry

A frustrated thirtysomething wife has a one-time fling with an unknown man who dies during the act in a hotel room, so she runs away and loses her wallet. A vertical-blinds salesman finds the wallet and enters the open room to place his blinds at the window, not knowing that a dead man lies nearby. He accidentally falls with the bar onto the head of the man and thinks he killed him and calls the woman who lost her wallet. They let it look like a suicide, call the police, and leave the room. The salesman's brother is a cop who is out for a career in the Police Department, and investigates the dead man. The cop is falling in love with the woman's best friend, and the woman finds out that the dead man was actually her husband's brother, who wanted to visit the family.
