Jake Bouchard (Dylan Everett), a shy 17-year-old, has finally scored a date with the incredibly wonderful Angie (Greta Onieogou). But plans quickly change when Angie gets kidnapped and the least likely person steps up to solve the case: Grandpa (James Caan). In a last ditch effort to rescue Angie from her captors, Grandpa re-enlists "The Devil's Scum," his old World War II intelligence unit, to band together with Jake to go on one last mission.
