chunk: Taken to the inside of the clock tower of Big Ben clock in London and tied up in it, while the final race is being held, Mater discovers that the camera did not function on McQueen, but quickly learns the criminals are planning to plant a bomb on him in his pits, causing him to break free and escape. Finn and Holley escape later, but realize that the bomb is on Mater's air filter. Mater soon flees on the race course when McQueen (who arrived at the pits) chases after him, while Finn apprehends Professor Zündapp. The other lemons soon arrive and outnumber Finn, Holley, Mater, and McQueen, but they are soon rescued by the arrival of the other Radiator Springs residents. Mater then uses evidence he had seen to reveal that Axlerod is the leader of this plot and placed the bomb on him, whom he soon confronts and forces to deactivate the bomb, before he and the other lemons are taken into custody, foiling the operation.
