Suri has what it takes to be a monster tamer - she just knows it! True, she's only tamed one monster so far: Byron, the giant-sized lap dog. Now she's on a journey to safely deliver Byron to the land of the giants: the Monster's Cradle.

To get to the Cradle, Suri and her friends must pass her through Bridgetown, a secretive place known for its remarkable inventions. The Bridgetown tollbooth charges an outrageous fee, but there's a catch: monster tamers may enter for free! All Suri needs to do is help the town with its 'little monster problem.' When she learns this problem involves a vengeful and strangely familiar dragon, her skills and courage are put to the test!
