DI John Major and DI Roy Carver are the top crime fighting duo in their Unit. But when an undercover sting goes horribly wrong, Major is gunned down on the job and killed. As an "asset" considered too valuable to lose, Major’s body is 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 has been lost in translation - quite a lot actually.
