Matt is worried Their relationship is in trouble. Cassie has been begging him to add role-play to their lovemaking, but the kind of role Cassie wants him to play leaves him cold. When he discovers her stash of erotic romance novels, he comes to suspect that what she really wants is dominance. Matt takes Cassie away for the weekend to celebrate her birthday. She is disappointed that the 'highlight' of the weekend is to be a costume party and that is not the kind of role-play she's fantasized about, but the party is at a BDSM club. Cassie agrees to be his 'love slave' for the weekend and promises to obey all her 'Master's' commands. Matt is surprised at her enthusiasm and is turned on by her ready acceptance of his domination. At last, he understands her desire to role-play and Matt indulges her fantasies, along with a few of his own. However, the weekend away has changed their relationship and has taken them in a direction he hadn't foreseen. Now he's wondering if they can survive the changes.
