However his wife also has the same planned for her husband, seducing one of her many lovers into doing the job. Should these attempted murders not succeed, the husband will have to carry on being blackmailed by his wife for his incestuous affair with his 16 year old daughter. Since the daughter has her own lethal romantic agenda, things don't go quite as planned.
