Anastasia Black's retirement from saving the world is interrupted when her new house unexpectedly travels through time and space to an alien leisure planet under siege.

In Australia's ancient past, Anastasia and Eddie offer to help two great hunters track down the ferocious beast which has been threatening their people.
