Both Stephen Graham and Daniel Mays are known primarily for taking on dark, gritty roles – but in the first season of police comedy Code 404 the pair showed that they have a lighter side as well, with the series becoming Sky's most-watched comedy in eight years.


Now the duo are back as Roy Carver and the artificially augmented John Major respectively, with a new case to solve – not to mention a fair few personal difficulties to work through following some revelations that came to light at the end of the last run.

Read on for everything you need to know about the second series, including plot details and which stars have joined the cast.

Code 404 series 2 plot

The story picks up again a month after the events of the series one finale, and John and Roy are no longer on very good terms following the revelations that came to light last time they spoke. But they'll have to resolve their differences soon – because there's a brand new case for them to solve.

The official synopsis provided by Sky reads, "Crime fighting duo of the future, DI Carver (Stephen Graham) and his AI-driven partner DI Major (Daniel Mays), are back!

"When a 20-year old cold case is reopened, the pair are forced to work through their differences and are thrown back into the action. But with an impending divorce to wife Kelly (Anna Maxwell Martin), the return of his long-time absentee dad, and danger lurking around every corner, the pressure seems to be getting to Major. However, much to Carver’s concern, his glitchy behaviour is more than a typical update and reboot can solve. Our cyborg hero may be looking at terminal failure."
