The Ex" follows Tom Reilly (Braff) and Sofia Kowalski (Peet) as they move from New York City to a small suburban town in Ohio with their newborn son. Tom, a straight-shooter who can "smell bullshit from a mile away," has just been fired from his job as a resident chef and has conceded to take a position with Sofia's father (Grodin) at a free-spirited advertising firm. Things get awkward when Tom realizes he's working with one of Sofia's high school flings, Chip (Bateman). Chip, arrogant and hard-nosed, has become one of the premier creative-types in the Ohio advertising arena, all without the use of his legs. Having never forgotten his one night with Sofia, he makes attempts at ruining Tom's life, all while wooing Sofia and her parents. Unfortunately for Chip, Tom's keen olfactory senses are starting to kick in.
