Tom, Zoe and Danny return for more save the world antics. This series covers a lot of story line. The peak of the strong relationship between Tom and Harry continues for the first few episodes, but signs of strain show towards the end of the series, ending with Tom shooting Harry! Tom starts his "becoming weird" phase after his private life takes a beating etc. as does Zoe's. Ruth joins the team (you know the weird one who talks funny), and there's plenty of good action and stories. Quite a sad ending to the season and the original trio.
