Pretty young Debbie has disappeared, lured away from home by members of the innocently named Healed Hearts Foundation. Rumours abound that the secretive organisation deals harshly with young women, coercing them into acts of submission and subjecting them to humiliating public punishments in order to secure their compliance.

Debbie's beautiful and curvacious sister, Kate, desperately worried for her sibling's safety, infiltrates the organisation, but the wouldbe rescuer soon finds herself trapped. Obliged to perform sexual acts and made to submit to cane, strap and paddle, Kate begins to despair as events spiral out of control. Can she save herself as well as Debbie, or are the two young women doomed to a life of humiliation and submission?
