Aimed at four to six-year-olds, Tommy Zoom deals with the everyday problems of life, especially the ecological and ethical - leaking taps, saving electricity, finding someone else's lost property.

Each episode begins and ends with a live action sequence, narrated by Daniel (Tommy's dog), in which Tommy is faced with a dilemma. Daniel will pose the question "What should Tommy do? What would Tommy Zoom do?" The show then switches to animation to show Tommy Zoom foiling a plot by Polluto which has some link to whatever problem the real Tommy currently faces. After saving world "in a zoom", the live action element is re-introduced, and Tommy is seen to make the right choices and solve whatever problem he has created.
