Nonfiction writer Benry Noir is single and needs a date for a wedding. If he doesn't attend the fun-filled function, the two grooms (and his dearest life-long friends) will be offended. The wedding can't be missed, and Benry doesn't want to go alone, so he places an ad online for the perfect date. When the advertisement fails, he decides to borrow his best friend's lover Just for a few days.

Just's boyfriend Armin loves his mate, but sometimes he seems to like work and travel more. When Benry first asks to borrow Just for the wedding, Armin refuses. But an opportunity to take a trip to Greece changes his mind. Still, Armin has strict rules the two men must follow, or there will be hell to pay.

When Benry and Just are alone together, they're on their best behavior and act as complete gentlemen. As hard as it might be to resist Just's charms, Benry manages to comply with Armin's rules. But once the wedding is in full swing and alcohol flows freely, the rules are forgotten, unravel, and break.

Will their indiscretions ruin Benry's friendship with Armin? He thinks he has found the perfect mate, but will things work out between them, or will Just disappear when the weekend ends?
