An interstellar warship protects survivors of a decimated civilization with a race of android predators in hot pursuit in this dark update of the 1978-80 space adventure. Unlike its `Star Wars'-influenced predecessor, this `Galactica' is a decidedly grim saga that portrays the Cylons as creatures that rebelled against their creators, who soon discover their foe can infiltrate their `ragtag fugitive fleet' by taking human form.
