Tom Chadwick

Played by Chris O'Dowd

Tom is feeling pretty lost and without direction in life after recently breaking up with his girlfriend of five years and being made redundant at his "pretty sexy" job reconstructing car accidents and assessing claims for an insurance company. But the unexpected inheritance of a chest full of old curios from a distant great-aunt sets him on a quest to trace his family tree and -- in the many unusual directions his journey takes him -- to find out who he is and what his place in the world is.
