One bright morning, the Steam Team are looking forward to doing their jobs for the day. Thomas is especially excited. He explains that he and Rosie have a delivery for Norramby Beach where they're building new beach huts in time for the summer.
Thomas soons speeds off to find Rosie and the Fat Controller. The engines are soon loaded with wood and sent on their way. As they chuff merrily along, they admire the beautiful views and sing summer songs. They are having such a lovely time, that they don't notice that they're almost at the seaside until Thomas declares that he can see the donkeys. Just then, Thomas spots a new bridge that has only just been finished. It looks very scary and Thomas doesn't want to cross it.
When Rosie looks back, she sees Thomas slowing down. He calls to tell Rosie to carry on without him. Rosie is confused and asks Thomas what's wrong, but the little blue tank engine is too embarrassed to say. Eventually, Thomas admits that he is frightened of the high bridge. Rosie laughs which makes Thomas very upset. Rosie apologises for laughing, but admits that she didn't think Thomas was scared of anything. Thomas tells her that everybody is scared of something. Rosie now feels silly and has a plan to make it up to Thomas. Rosie suggests they cross the bridge as a team. Thomas feels frightened, but he doesn't want to let anyone down. As they cross over the bridge, Rosie tells Thomas a joke to take his mind off it and before he realises it, they have crossed the high bridge.
Thomas thanks Rosie for her clever plan and admits it wasn't so scary after all and Rosie thanks Thomas for teaching her that it's okay to be scared. Then, the two friends set off to deliver their wood.
- Thomas and Rosie sing a line from the 1963 song "Summer Holiday" by Cliff Richard and the Shadows.
