Spynosaur, the world's only dinosaur spy, and his sidekick Amber race to investigate a distress beacon emanating from the Arctic Circle - the last location of Spynosaur's long-lost father, super-spy Abner Gambit. They trace the beacon to an underground hideout, where they are met by an army of mecha penguins ... and rescued by Spynosaur's dad, who has been accidentally frozen in ice for the last thirty years. Father and son team up to complete Abner's unfinished mission - to track down enemy agent The Purple Spyder, who's in possession of the P.L.O.T. Device, a machine that can predict spies of the future. The race is on to find the device, but with very different approaches to spying, can Spynosaur and his dad put aside their differences long enough to save the day ... and the future?
