Finbar Dolan is lost and lonely. Despite escaping his blue-collar Boston upbringing to carve out a mildly successful career at a Madison Avenue ad agency, he’s a bit of a mess and closing in on forty. He’s recently called off a wedding. Now, a few days before Christmas, he’s forced to cancel a long-postponed vacation in order to write, produce, and edit a Super Bowl commercial for his diaper account in record time.
