At sunset, when their work is done for the day, a crane truck, a cement mixer, and other pieces of construction equipment make their way to their resting places and go to sleep.
Told in rhyming text, Excavator, Bulldozer, Crane Truck, Dump Truck, and Cement Mixer will all need to work together as they tackle their biggest job yet--a massive building.
It is Christmas Eve, and all the construction vehicles are finishing up work on the site, and when they leave they find that there is a special present waiting for each of them.
