Dennis, who works for the CIA, has just completed their latest mission and goes to the bar in Las Vegas, as is his ritual after every successful mission. There, he manages to save a busty blonde who offers him a bit of kinky fun.
Dennis rejects this offer because the terrible memories of his past have been triggered. (He's a foster with a sordid past.)
The next day, his best friend, Adam, invites him to drink with his sister. Dennis gives in after slight coercion and gets to meet Adam's sister, Elena, whom he considers young but absolutely gorgeous. Adam leaves the bar with a woman, and Elena ends up in Dennis's apartment, where their first kiss happens. Adam, the next morning, finds out that his cover has been blown and so he has to keep Elena safe, as she could possibly become a target.
