The Legends find themselves in 1870 to fix the anachronism which happens to be at P.T. Barnum's fledgling circus. However, Nate (Nick Zano) and Ray (Brandon Routh) accidently free a saber toothed tiger, creating a bigger problem. Meanwhile, P.T. Barnum (guest star Billy Zane) is on the hunt to capture Nate and Ray to make his show even more exciting for the crowd.
