It has been well over a year since Lily met Thomas the tank engine on Sodor, Lily visits Sodor, and Thomas, as often as she can. So when her family decide to move to Shining Time, she was ecstatic. But when she finds a metallic purple whistle, (which is filled with magical gold dust) it uses the small amount inside to take Lily to the Island of Sodor. Now she's stranded, alone, with almost no way to get home, and to top it all off, Diesel 10 is back! It is up to Thomas to find his best human friend, Lily, and bring her home.
