The race is on for Fireman Sam and his team. Gareth is taking the Science class to see the Aurora Borealis but, while preparing Bessie, accidentally trips, knocks off the brake and tumbles from the train. As a cabin fire also breaks out, Gareth watches in horror as the train speeds off without a driver and the children on-board! The fire crew is called but their path is blocked by snow and ice and so Sam makes a bold decision, leaping from the helicopter to ski towards the runaway train. It's a Race Against Time to stop the train before it reaches the end of the line!
