All aboard for fun-fueled adventure in Thomas the Tank Engine's first film ever, starring Peter Fonda, Mara Wilson and Alec Baldwin. For as long as anyone can remember, the Island of Sodar has been the realm of enchantment, innocence, and talking trains. The steam engines suddenly find themselves heading for a heap of trouble at the claw of the evil Diesel #10. This one's a totally terrible train with devious plans to dominate the other engines by finding and crushing their dwindling supply of magical gold dust. Lily (Mara Wilson) has a hunch that her grandfather (Peter Fonda) holds the key to rescuing the little trains in his workshop on Muffle Mountain. She meets up with Mr. Conductor (Alec Baldwin) and, along with a caboose of colorful characters, they return the sparkle to their island!
