It was meant to be a one-night stand, not "I do." Joe Kaminski likes to go with the flow, a good trait to have as a young artist living in London. His laidback approach to life makes him a fish out of water when he's hired at P&B Designs, a high-powered PR agency. The money's good, but with his poor planning skills, he doesn't see it lasting. Harry Byrne likes his life the same way he likes his PowerPoint presentations: structured. Known for his dynamic personality, Harry suffered a blow when his seven-year relationship fell apart, souring his mood. The last thing on his mind is getting into another relationship, especially with a man who can barely make it to the office on time. They're not even supposed to like each other. But five years later, Joe and Harry are getting ready to tie the knot. They should've known it was only a matter of time before everything starts to fall apart: obstructive friends, well-meaning but meddlesome family, a hovering ex, international incidents, fires, pregnancies, and an airport chase. It seems their "I do"s were doomed from the start.
