Henry and Jo discover there is a fine line between pleasure and pain when the death of a successful businessman and devoted husband points to a form of ritualized punishment. Henry learns it may be all a question of trust. The man's "domination therapist" comes under scrutiny as a murder suspect, who also wants to take on Henry as a client and help him work through his own issues. Flashbacks reveal Henry's emotional story of betrayal after he shares his secret with his first wife, Nora (guest star Victoria Haynes). Meanwhile, Abe is flabbergasted when the object of his intense passion — Maureen Delacroix (guest star Jane Seymour – Dr. Quinn, Medicine Woman), his two-time ex-wife — reappears with a tempting offer.
