Thirty-something Tim has reached a crossroads. Not only is he stuck in a dead-end job at Computer Universe, but he's locked in a custody battle with nice-as-nettles ex-wife Judith (Dolly Wells) over son Marcus (Jude Wright), a precocious nine year-old who is as happy spending time with his dad as a PETA member would be modeling fur coats. Tim's world is shaken, and most definitely stirred, however, when he's accidentally recruited as a trainee spy for MI5, going from zero to hero.
