Rent Everybody Wins (1990)

Things certainly aren't easy for a jaded private detective on the weird streets of Connecticut, just ask down and out private eye Tom O'Toole (Nick Nolte). Hired by a mysterious woman convinced that a local, juvenile teen banged up on a murder charge is innocent, detective Tom O'Toole is suddenly sucked into a twisted world of split personalities, oddball locals, reformed drug runners, religious fanatics, demented biker gangs, corrupt politicians and a deadly secret that "goes all the way to the top of the mountain''. But who can be trusted? Is it all a big cover up? Is it all lies? Is detective Tom O'Toole being duped? Or is it all the demented fantasies of an unstable woman's deluded mind?
