Years ago, Becky was mocked by her friends in high-school as Piggy Face. Now she is a bride and her bitchy friends are invited at the wedding party as bridesmaids. Why she invites them are left behind the scenes but you should see her best (but still unmarried) friend's face when she meets Becky's groom, a handsome and lovely big guy, Dale. By the way Dale is portrayed by Hayes MacArthur who played "Big Handsome Guy" in The Adventures of Big Handsome Guy and His Little Friend (2005). Becky's best friend (and most bitchy one) Regan is played by Kirsten Dunst. Regan is used to be the best in everything, her perfectionism always balances on the edge of boredom and amusingness. The rest of Becky's friends are pretty much dysfunctional too: Gena, a drug addicted girl with head in the clouds, played by Lizzy Caplan; Katie (Isla Fisher) who drinks too much of Cosmo cocktails and sniffs lots of cocaine which make her go out of the rails and throws to embraces of her former classmate Joe (Kyle Bornheimer) who used to sell her a weed in high-school. As the action unfolds the wedding party spirals out of control immersing all the key characters in the night of chaos and debauchery.
