Synopsis:
Rip Hunter and his team of time travellers journey to 325 B.C. to discover the secret behind a recently discovered stone tablet. The tablet supposedly reveals the location of Atlantis, but the writing has been worn away. When they reach 325 B.C., Rip's team meets Alexander the Great, who is in possesion of the tablet. The writing is legible, but it is missing a map.

Alexander tells Rip the tablet came from Aeaea, so Rip takes his team further in the past to locate the island from which it came. On the island of Aeaea, Rip meets Circe, whom is a supposed sorceress. Bonnie exposes Circe's magic as a fraud, then then find the tablet, complete with map.

Finally, Rip takes his team to the time and location given by the tablet, where they discover the lost continent. The island is inhabited by an advanced race from Jexjera. Rip helps them escape from the island, then watches the island sink into the ocean.
