Maurice Flitcroft, a dreamer and unrelenting optimist, managed to gain entry to The British Open Golf Championship qualifying in 1976 and subsequently shot the worst round in Open history, becoming a folk hero in the process.
Code 404 revolves around two Detective Inspectors, DI John Major (Daniel Mays) and DI Roy Carver (Stephen Graham), who are the top crime fighting duo in the Unit. But when an undercover sting goes horribly wrong, Major is gunned down on the job and killed.
How will the SIU function without Major? It doesn’t have to. 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. Somehow, Major’s error-strewn hunches and Carver’s scrambling to make good allows them to just about scrape by.
