Kassie (Jennifer Aniston) and Wally (Jason Bateman) are best friends. Being unlucky in love, Kassie has decided to have a child using artificial insemination. Wally doesn't like this idea, but he isn't capable of admitting to himself, let alone to Kassie, that he's in love with her. At Kassie's artificial insemination party, Wally gets very drunk and spies the sperm donor's sample in the bathroom. Wally was way too drunk to know what he did that night, and Kassie has moved away because she doesn't feel that New York City is a place to raise a child. Now 7 years later, Kassie has moved back with her son Sebastian. While she is looking to get Roland (the sperm donor) more involved in their lives, Wally can't help but notice the many striking similarities that he and Sebastian share.
The most unexpected comedy ever conceived.

Look at us. Running around, always rushed, always late. I guess that's why they call it the human race. What we crave most in this world is connection. For some people it happens at first site. It's when you know, you know. It's fate working its magic. And that's great for them. They get to live in a pop song; ride the express train. But that's not the way it really works. For the rest of us it's a bit less romantic. It's complicated and it's messy. It's about horrible timing and ...
