The annual computer Horizons convention has brought the Hardys to New Orleans. Folks call the city the Big Easy, but if the boys aren't careful, they could both go down hard. The trouble begins in a jazz club down on Bourbon Street. Together with their friend Vanessa, they run into Billy Barta, a local guy from the convention, and it's one encounter they'll never forget....

Billy asks Vanessa to dance. Joe gets jealous, then gets into a fight. The next day Joe gets arrested -- for the murder of Billy Barta! Frank bails his brother out, but if they don't find the real killer, Joe's bound to take the fall. Billy Barta was into some serious criminal computer action...and Frank and Joe are about to face some serious southern heat!
