A stormy night leaves Bob, Roley and the team with lots of work to do. But they’re not too busy to help some baby birds whose nest was blown away by the wind. Nothing can stop Roley and his friends from coming to the rescue! Things get pretty noisy when Bob and his crew are called in to replace Mr. Beasley’s banging pipes and boiler. With Bob working on the boiler upstairs and Mr. Beasley working downstairs, they finally manage to sort through the confusion and noise to get the job done! Roley is exited about his new friend, Timmy the tortoise, and the building yard seems to be the safest place to keep Timmy while they search for his owner. But when Timmy turns up missing, it’s Farmer Pickles who finds him in an unlikely place. Roley, the hardworking steam-roller, becomes a runaway "sleep roller" when he rolls out of the building yard while still asleep! Fortunately, his best friend, Bird, flies in search of help. Can Bob and the crew find a way to rescue Roley before he flattens the town?
