Lofty, Scoop and Muck are clearing some land near the new bridge, while Bob, Dizzy and Roley repair the pavement in the town centre. Lofty's scared of heights so, rather than cross the bridge, he goes the long way round, past Spud's field. The naughty Scarecrow, looking for some fun, decides to follow Lofty. Despite Spud teasing him about his fear of mice and heights, Lofty helps to clear the site by piling up some logs. When he's finished, the disheartened Crane returns to the yard. Back at the bridge, Spud is causing more havoc, hurling mud pies at Muck, and Scoop. Running away from the angry Machines, Spud climbs the pile of logs. Suddenly, the one he's standing on rolls over, hits a boulder, and catapults Spud into the air and over the side of the bridge. Luckily his belt catches on a bush, stopping his fall. The only machine that can rescue Spud is Lofty the Crane, and Scoop races back to the yard to fetch him. Lofty will have to use all his courage to overcome his fear of heights - not to mention Scary Spud! Wendy phones Bob to tell him about Spud's accident and Bob, Roley and Dizzy race to the bridge. When they arrive, Spud is still hanging on - just! Lofty inches towards the edge - but can he conquer his fears? Of course he can, with his eyes tightly shut and a little help from his friends. Spud is saved and rewards his new friend Lofty with a big hug.
