The Andromeda is attacked by mysterious beings from an alien realm. The crew mounts a counteroffensive, despite the incredible odds against them -- not to mention the fact that the enemy is invisible. Worse still, the ship's A.I. avatar Rommie (Lexa Doig) has been captured, and is presently squirreled away on a planet consisting of a network of labyrinthine tunnels. ~ Hal Erickson, Rovi
