In a bunker hidden deep beneath London live five extraordinary kids: meet world-famous hacker Jack, gadget geek Charlie, free runner Slink, comms chief Obi and decoy diva Wren. They're not just friends; they're URBAN OUTLAWS. They outsmart London's crime gangs and hand out their dirty money through Random Acts of Kindness (R.A.K.s). Their latest mission – hacking the bank account of criminal mastermind Del Sarto – has landed them in serious trouble. Del Sarto is going head-to-head with MI5 for control of Proteus, an advanced quantum computer able to crack any code and steal top-secret documents in nanoseconds. It's down to the URBAN OUTLAWS to use their guile, guts and skill to destroy Proteus, avert world domination . . . and stay alive.
