Murder Sees the Light (1986)

The awkward urban private eye, Benny Cooperman, confronts a murder mystery in the wilds of Algonquin Park. He stumbles into some interesting characters, including a famous evangelist on the lam, his put-upon mistress, a weird sexy woman, and a complex charming old lady. Naturally, Benny suffers some misadventures trying to navigate the bush country, much less solve the case.
