Plot summary
After a drunken Bailey crashes his jeep into a stoplight post, he blacks out and has a vision of an alternate reality of what life would be like if his parents never died in the car accident six years ago. In this alternate world, set during a weekend of planning Nick and Diana Salinger's 31st anniversary party, all of the siblings are insecure with their parents, whom they cannot stand up to. Bailey is revealed to be living with Will and both of them work as roadies for a heavy metal band after Bailey dropped out of college and never stopped drinking or grew up.
Charlie appears better off having gone back to college, earning a Master's degree in architecture, and is a fairly wealthy man working in a prestigious company. But like Bailey, Charlie never met Kirsten or ever grew up. He has to deal with his pregnant girlfriend's abortion, where he meets Kirsten for the first time working as a medical consultant at an abortion clinic. Julia also never grew up and has been engaged to Justin for years, which changes when she meets Griffin for the first time and loses her virginity with him.
Claudia, on the other hand, is a home-schooled violinist, having gone on various world tours in which she wants to quit her profession for a little rest. All of them, nevertheless, come together for their parents' anniversary party at Salinger's Restaurant. At the end, Bailey wakes up from his fantasy and decides to seek help for himself.
