Double Exposure

I can't believe that after one passionate night, I realize I've got the wrong guy completely.
It was supposed to be a simple mission. She goes to the airport to pick up the best man, a doctor named Harry, for her sister's wedding, and that's it. And yet, one look at Harry and Kate's heart is aflutter. How sexy he is! Because he acts like a dour hero, Kate and the eyes of those around him are glued to him. She is infatuated with him. Kate, who is usually cautious about her love life, mistakenly thinks it is a special encounter… But when the night is over, the problem becomes clear. She finds out that he is not Harry but his twin brother, Hugh, who is working in Hollywood.
