Cruising
Cruising is the story of cop Steve Burns (Al Pacino), who has accepted the task of going undercover to investigate the murders of several gay men in New York City during the late seventies. He has no police backup, can’t tell his girlfriend what is going on, and all of the action takes place in gay S&M bars, which is not a milieu with which he is all that familiar. So he packs a suitcase and moves to the gay part of town, where he spends all of his time in bars hunting for the serial killer or hanging out with his nice neighbor, Ted (Don Scardino). As time passes, he changes, losing sexual interest in his girlfriend and having doubts that he can handle this situation. Things get more and more out of his control until he thinks he has found the killer.
