Rick Deckard had left his career as a blade runner and the gritty, neon-lit labyrinth of L.A. behind, going to the emigrant colony of Mars to live incognito with Sarah Tyrell. But when a movie about Deckard's life begins shooting, old demons start to surface. The most bizarre and mysterious is a talking briefcase--the voice belonging to Deckard's most feared adversary. The briefcase tells Deckard that he's the key to a replicant revolution back on Earth. Deckard must deliver the briefcase--the secret contents--to the replicants of the outer colonies before he is tracked down and killed. Is the briefcase lying? Who is really after Deckard? And who is the little girl who claims her name is Rachael? Once again Deckard is on the run from a sinister force determined to destroy him--and already closing in.
