Captain Marco DeWinter is a cop on a mission when a brush with death lands him in the hospital. Regulated to mandatory time off, he begins to re-examine his priorities and entertain the idea of his sexy ER doctor having him on the receiving end of a set of handcuffs. Ever since Marco discovered Dr. Jasmine Jovanovich's secret life as a dominatrix, he's been eager to feel the bite of her Stiletto in his back as she makes him worship at her feet.

Jasmine agrees to be his guide into the darker pleasures, and is delight when he dives in with the same enthusiasm as he does his police work, that is until he makes her question her "Cavern Only" policy, and wants to blur the lines between her professional and personal life. When Jasmine is caught in the fallout of one of his cases, Marco must convince her that not only can she trust him to keep her body safe, but her heart as well.
