John is travelling from his middle-of-nowhere seaside town to the big city. He's visiting his friend Grant for the first time since Grant started college. John is shy, harbouring a sissy secret, while Grant is handsome, muscular, confident and outgoing. John was under the impression his night would be just him and Grant. Until Grant reveals a bombshell... They're going out to a fancy dress party, where the only attendees permitted entry have to be male and female couples. Grant has a masculine superhero costume set aside for himself, and a feminine PVC catsuit with mask and stiletto boots for Joanna to wear. "Who's Joanna?" John asks, innocently. "You are," Grant tells him. Can John successfully cross-dress and become Joanna? Can she convince everyone at the party she's Grant's legitimate girlfriend? And what if she just happens to want to do a little more than pretend?
