Bold And Brave is the 217th episode of Thomas and Friends.
Summer is approaching the Island of Sodor and Thomas is asked by Sir Topham Hatt to collect deck chairs and windbreaks for the beach. Unfortunately, Diesel tells him of the "curse of the cliffs," in which a terrible fog comes down on the cliffs and causes the first engine of the holiday season that goes round the headland to disappear. This ends up worrying Thomas, especially when Harold warns him of fog near the headlands. This ends up leaving Thomas frightened.
Thomas later finds Ben outside of a tunnel; Diesel had told him that a monster is lurking inside. Thomas goes to investigate and hears a strange noise and sees two eyes in the tunnel. However, he finds that the eyes actually lights and the noise is really a generator powering them. Ben thanks Thomas and goes on with his job.
Thomas puffs onwards, still afraid of Diesel's warning of the "Curse of the Cliffs." He soon comes across the fog while puffing towards the headlands, but thinks about what Diesel told Ben wasn't right and that he might also be wrong about this as well and bravely goes on. Suddenly, the mist rolls away and makes Thomas realize that Diesel must've been trying to scare him. Thomas then states that he shouldn't listen to Diesel and only listen to himself.
