Samantha Who?:

Sam discovers more and more the extent of her former bad behaviour and decides the easiest way to deal with it is to scream 'I'm sorry' as her outgoing answer machine message. But she perks up when the doorman hands her a bridesmaid dress. Overjoyed that somebody must have liked her, Sam jumps at the chance to assume her role as bridesmaid in a friend’s wedding, especially as Todd is the photographer and Dena is coming along to help.

However she shows up to the wedding only to learn she's been uninvited by the bride. At first dejected, and then motivated by the challenge of vindication, Sam sets out to apologize and be re-accepted by the bride, as a result leaving Dena in the dust yet again. But the new Sam knows how to make amends and is soon on the road to redemption.
