Locked in a battle with a Drone Command Ship, the Destiny is surprised by the arrival of the Aliens that abducted Rush and Chloe.

Eli and Rush have found a way to identify the location of drone mother ships using the Destiny's long range sensors. The bad news is that the Drones seems to be awaiting them at every possible stop along Destiny's path.
