Now, Voyeur (2011)

Homebound with a broken leg and left without phone or internet service, a bored woman starts to spy on her neighbors activities with her powerful binoculars. When on successive days she sees a photographer in a nearby apartment bind, gag and force his lovely models into trunks which are then loaded in an SUV and driven away, she suspects foul play. She finally convinces her roommate to break into the neighbors apartment and gather evidence of foul play. When the man returns unexpectedly, he captures the roommate and forces her to admit why she was searching his apartment. Soon both roommates are topless, roped and muzzled and can only mew in terror when the photographer explains his scheme to eliminate the pretty witnesses.
