When brother & sister Paul (8) and Kat (12) are shipped off to spend 4 months with their super-strict grandma, they don’t expect to discover Granny was once a world-class secret agent. But when her old friend-turned-nemesis has her kidnapped, it’s up to Paul and Kat to team up, gear up, and save the day … spy-style! They’ll have to train like agents, chase down villains, and stop a satellite-powered vaporiser before it destroys their mum’s space station, all before bedtime.
