Sydney Cole, a rebellious teen, is taught a lesson in obedience when her older sister invites a dominant friend over. The stranger, a stern and imposing figure, takes charge, binding Sydney's wrists and ankles to her bedposts. She squirms and protests, but her defiance only fuels her captor's desire. Olivia, Sydney's sister, watches in horror and arousal as the stranger teases and torments Sydney with a vibrator, bringing her to the brink of orgasm before denying her release. Sydney's cries of frustration soon turn to moans of pleasure as she surrenders to her new mistress.
