Peepers.

A rag-tag group, led by the eagle-eyed Steve, take to Montreal's chilly rooftops under cover of night. They're on the prowl for the perfect peep desperate to glimpse a "hottie hookup," a "panty party" or a "big booty buffet" through unshuttered windows. But their lives are about to change. Enter Annette, a brazen academic who turns the tables by setting her sights on the peepers themselves. Soon it's a battle royale for rooftop supremacy will these die-hard obsessives manage to defend their turf, or will peeping as they know it never be the same?
