25-year-old housewife Sadie Miller, desperate to salvage her marriage with her cold, unfaithful husband Shawn, tries to learn about sex from a professional escort.
But there, she crosses paths with Guy Hawkins—the mafia boss of the Hawkins Syndicate, who numbs his pain from losing his family as a child through violence and BDSM. Drawn to Sadie's innocence and embarrassment, Guy proposes a one-month contract: she'll accompany him under the terms of an S&M agreement.
For Shawn's safety, Sadie accepts. Amidst training, humiliation, and temptation, she finds herself growing emotionally dependent on Guy.
After weathering emotional turmoil and life-threatening danger together, Sadie and Guy move beyond their master-servant roles. They become true partners, bound by love and a vow to each other.
