Harry Reems and Darby Lloyd Raines are a couple who have built up a thriving business around each`s ability to satisfy lovers of the opposite sex. They started out with a plain ol` escort service, but soon found out they could make more cash doing the kinky stuff. So now they specialize in supplying well-paying customers with customized sexual services. The money`s rolling in and they seem to be very much in love, but trouble`s brewing. Darby overhears Harry pillow-talking with one of their workers with whom he`s been spending his off-hour sexual energies, and it turns out Harry and his new squeeze are planning to rub Darby out and take over.
