Synopsis:
Steve Trevor and Diana Prince discover a cave painting revealing Wonder Woman was in the past along with her mother and her former selves, Wonder Girl and Wonder Tot.

Diana recalls that by splicing together film and with the aid of Amazon magic, she was able to do the impossible, exist as three separate beings in the same time. Together they battled Multiple Man, a shape-changer created in a nuclear blast. After defeating Multiple Man, Hippolyta fashions pieces of him into a bracelet. The bracelet possesses the Queen, who then forces herself into exile in the past.

The Wonder Family follows her. The bracelet is restored and Multiple Man again threatens them in the past as a dinosaur. They defeat him once again, when lightning strikes him. Then they return to the present. The thankful cavemen record the battle in a series of cave paintings.
