Red Thread (2005)

Billy works as a maintenance guy in a luxury apartment complex. Tamara, a new tenant, is engaged to Mark and is about to become a trophy wife. Miss Johnson, the widowed apartment complex manager, can think of nothing but ways to lure young Billy into her lair and seduce him. One night, right after her fiancé has gone on a business trip, Tamara gets injured. There is no one to help her except the maintenance guy. Tamara and Billy unexpectedly discover a friendship that could lead them both to realizing the dreams they'd nearly given up on, if only Tamara weren't engaged and Miss Johnson weren't watching.
