Sky One’s hit comedy Series 1 and 2. Series 1 John Major had it all: wife, best friend, glittering career in the police force... when his cover was blown and he met an untimely death. One year later, he's back - part AI and better than ever... or so he'd like to believe. Full of glitches, he's got to track down the person who shot him, prove himself as a cop so as not to get shut down, save his marriage and his friendship with his partner to boot. Series 2 DI John Major and DI Roy Carver were the top crime fighting duo in the Unit but when an undercover sting went horribly wrong, Major was gunned down on the job and killed. As an ‘asset’ considered too valuable to lose, his body was fast-tracked into an experimental Artificial Intelligence project to bring him back from the dead. The only problem is, Major 2.0 may look like and sound like the original, but something was lost in translation - quite a lot actually. Oh, and if that wasn’t enough, thinking her husband is dead, Major’s wife has fallen in love with Carver. Somehow, Major’s error-strewn hunches and Carver’s scrambling to make good allows them to just about scrape by – but for how long?
