Nobby has everything a man from Grimsby could want, including 11 children and the most gorgeous girlfriend in the northeast of England.

There's only one thing missing: his little brother, Sebastian, for whom Nobby has been searching for 28 years, after they were separated as kids.

Nobby sets off to reunite with Sebastian, unaware that not only is his brother MI6's deadliest assassin, he's just uncovered plans for an imminent global terrorist attack.
