Mark (David Mitchell) and Jeremy (Robert Webb) are still sharing their fiat in south London, but their journey through life is becoming ever more complicated — and bitterly funny. Hear their deepest, darkest and most socially unacceptable thoughts as they navigate their way through a surprising role reversal: Mark, the inhibited, obsessive white-collar drone, is forced to rethink his life after becoming a father, whilst wannabe musician Jeremy, a lazy man with big ideas, finally finds himself in possession of money, power — and, finally, responsibility. Follow Mark and Jeremy from the birth of Mark's baby to his christening. We also meet Mark's parents for the first time, when the boys attempt to celebrate a traditional family Christmas. And a disastrous New Year's Eve party crawl culminates with Mark and Jeremy facing choices that could end their friendship - forever.
