Cars 2 features a spy mission involving Mater and Finn McMissile.
In the film, Mater is mistaken for an American agent and becomes involved in an international espionage plot. Finn McMissile, a British spy car, and Holley Shiftwell recruit or work with him while investigating a conspiracy connected to the World Grand Prix and Allinol fuel.
Cars 2 was released in 2011 and expanded the franchise beyond Radiator Springs and the Piston Cup. Its action moves through locations including Tokyo, Porto Corsa, and London. Mater's accidental involvement forms the central comic storyline, while Lightning McQueen competes in the international race.
The film is sometimes confused with Cars on the Road, a later streaming series that follows Lightning and Mater on a road trip. Cars 2 is the franchise's second feature film and the first to place Mater directly in a spy-adventure plot.
