John and his buddy, Jeremy are emotional criminals who know how to use a woman's hopes and dreams for their own carnal gain. Their modus operandi: crashing weddings. Normally, they meet guests who want to toast the romantic day with a random hook-up. But when John meets Claire, he discovers what true love – and heartache – feels like.
