Thomas & Friends: All Engines Go!

Harold the Helicopter longs to see the Northern Lights, a dream that drives his journey across the island. However, the overly‑excited engine race ignores warnings to stay away from the Sodor Suspension Bridge, leading to chaos and causing his plan to go awry.

"It All Adds Up" is a programme presented as an episode, falling under the genre of a standalone instalment. The title itself hints at a narrative where various elements combine to drive the story forward, and the format is that of a single‑episode adventure. The central thread follows Harold the Helicopter, who has long nurtured a wish to witness the Northern Lights. His ambition sets the stage for the events that unfold, positioning his desire as the catalyst for the episode’s action. Complications arise when an engine race, characterised by an over‑enthusiastic approach, decides to disregard the clear instructions to avoid the Sodor Suspension Bridge. Their decision to press on despite the cautions creates a clash between Harold’s peaceful goal and the race’s reckless momentum. As a result, Harold’s plan to see the aurora is thrown into disarray. The combination of the race’s imprudent behaviour and the proximity to the bridge ensures that the original dream does not unfold as intended, leaving the audience to see how the situation unravels.
