The Initiation.

In The Big Catch, Marcelo Lagoas makes a delivery to a new house on his route where he accidentally discovers the existence of a secret society of men who have sex with men! Once inside, he see's things he shouldn't unless he's been initiated into the club, so he must join. (or lose his tip for the original delivery!) Fortunately, the initiation ritual is one big orgy , which is right up Marcelo's alley!
