The high-adrenaline adventures of White Watch, a team of London firefighters. Leading the crew is Kev, a good man injured and betrayed during the worst fire of his career. Standing by Kev's side as he returns to work is his gutsy girlfriend Trish and his cocksure friend and fellow firefighter Mal. Other members of the crew include the fearless Ziggy and the mysterious new boy Dennis. An experienced fire fighter is badly injured and spends almost a year recovering at home. Now he returns to work, but is he as emotionally and physically sound as he thinks he is?
