The Cortians are back, and they want Echo.

After months of "playing target," the heads of the Alpha Line special forces department, Alpha One--Agents Echo and Omega--finally take a very special vacation on Tiniken, the "Eden planet," for some much-needed R&R. The pair kick back, relax, and play tourist, exploring this lovely alien world together.

But when they unwittingly cross paths with a Cortian slave ring and the Cortians recognize Echo as "Cortian Enemy Number One," he becomes their next target, and "Eden" displays a seamier side. Can Omega and the rest of Alpha Line find Echo before he is sold as a slave... or worse?
