Pier Groups(1979)

Two neighbors head for the famous New York City piers, one for some fun on a day off, the other because he has an assignment to prepare for his demolition company to put in a bid for the piers' destruction — "No one uses them," says his boss. The engineer, played by Johnny Kovacs, wanders through the piers checking out their architecture and again and again happens upon guys — including his neighbor, played by Keith Anthoni — getting it on.
