The Greek God of wine, women, and party, falls off a balcony during Mardi Gras in New Orleans. Now he has amnesia. All he knows is that they call him 'Big D', and he's a party animal who drinks too much and ought to give up alcohol for Lent.

Mandy and Brandy flashed Dionysus right before he fell. They're nice enough to take him to an AA meeting, and then back to their homes until he recovers his memory. Fortunately, they're not too nice to be naughty. They all agree that replacing a bad habit with a healthy one is the key to sobriety, and what could be healthier than sex? Will he come between friends before they know who he is? Will Zeus separate all of them, forever?
