After a monstrous storm on the Island of Sodor, a landslide unearths some very unusual footprints. Thomas and Percy are eager to find out what could have made them but obstacles and danger seem to appear around every bend in the track. With the help of new friends, a little digging, and a heap of courage, they discover the surprising answer and, along the way, uncover the true meaning of bravery.

A special guest arrives on Sodor with a big surprise and important jobs for Thomas, Percy and James. The engines meet new friends and discover suits of armour, coats of arms and legends of long-ago heroes. Then their bravery is put to the test when their new friend Stephen goes missing. Will Thomas find him in time? Will the engines discover the truth about the Island of Sodor's biggest mystery?
