Bill and Ben are working at the quarry and are bored of doing the same thing. Ben asks Bill if he can hear something different, to which Bill replies that he cannot hear anything different. Ben then states that everything sounds and looks the same and that they need a surprise. Before Bill could answer Ben, the Quarrymaster comes with a message from the Fat Controller that they have to go to the harbour.
Bill and Ben head to the harbour worried that they did something wrong and blame each other on the way. The Fat Controller asks Bill and Ben to shunt trucks while Edward is taking the children on a trip. Bill and Ben meet with Gordon, who asks them to behave here since they are on the Mainline. Bill teases Gordon about the time they saw him and thought that the harbour was the scrapyard. This makes Gordon cross, and he orders the twins to get his coaches ready for his evening train.
The twins start working to organise the trucks. They say to themselves that the work is easy as they know all about trucks, but they don’t. The trucks claim they want to help Bill and Ben to organise the harbour and the twins take their advice, not knowing that the trucks are playing tricks on them. Evening comes and everyone is complaining of how messed up the harbour was. As a result, the yard gets in a mess, causing Gordon to be late with the Express.
The next day at the quarry, the alarm goes off as a rock slide is about to occur. Bill and Ben wait for the workers to get in their trucks. Bill leaves with the Quarrymaster being left behind, but Ben waits as he climbs aboard and everyone gets out just in time as the landslide devastates the quarry. Bill and Ben hope that the Fat Controller would understand that it was not their fault. The next day, the Fat Controller arrives with Edward and praises the twins as heroes for saving the day. Bill and Ben think that being called "heroes" is quite a nice surprise.
