Lying, cheating, thieving—they’re the best undercover cops in the business. Liam Ketman (Nick Berry, Heartbeat) and Garth O'Hanlon (Stephen Tompkinson, Wild at Heart) take on false identities to infiltrate society’s underbelly and stop crime at its core. As they put their lives on the line, Liam tries desperately to hold his marriage together, while Gareth keeps his personal life a mystery.

The horrors of war are examined from the view points of lifelong friends (Linus Roache, Vincent Perez), who end up on opposing sides in the civil war in Sarajevo. One is an expert marksman, who trains the snipers used to terrify the city and the other becomes a freedom fighter, who rejects his friend's offer to gain an escape from the city. As might be expected, the two eventually have to face-off against one another.
