The traintastic crew are back on the rails. Trainee engines Koko, Wilson and Brewster with their young friend, Zephie and new trainees Hoot and Toot, try to keep everything rolling smoothly, but their curiosity and good intentions often signals trouble on the tracks. Action Chugger is in town making a movie and Emery lands the exciting job of assisting on the film set. Brewster is a little envious, especially as his job for the day is litter-picking. He worries that his fellow chuggers think he's a bit dull. Calley tells him that a job is what you make it and shows him that the litter-picking wagon can do some cool things. On his way to the shoot, Action Chugger has a jet malfunction and crash lands, right in front of Brewster. Using his new skills, Brewster saves the day. Action Chugger is so pleased, he takes Brewster to the film shoot as his special guest - so it turns out to be an exciting day after all.
