Paul and Angelina are old friends who dated in college, briefly, years ago, and recently reconnected via email. During their correspondence, they realized that they both regretted not taking up with each other back then, especially given their difficult and tumultuous first marriages after college. When Angelina is killed, she is offered a choice of what to do next and opts to have both of them return to when she and Paul first arrived at college and do it over again ... while remembering what happened to them over the years. They make many changes in the way they live their lives and find true happiness together. Although they don't repeat those mistakes they made before, they definitely find new ones to experience and explore.
