The Five-Year Engagement

In San Francisco, after a year's relationship, Tom proposes to Violet; she accepts. She's an experimental psychologist, hoping for a post-doc at Cal. He's a sous chef who runs the kitchen when the chef is away. When Cal falls through and she gets an offer in Ann Arbor, Tom agrees to support the move, turning down a job as chef at a new restaurant. The move requires postponing the wedding. At Michigan, Violet is in her element, but Tom is underemployed and frustrated; he's Stoic for a while, but when two years in Michigan become four, Tom's frustrations boil over, and on the eve of yet another wedding date, they must make a choice. Is there any other alternative?
