Director: David Solomon

One year after the events of Epitaph One, the world is still gripped by the cataclysmic effect of the wiping technology. Echo and her team rescue Topher from Rossum when he sends word that he has the solution, and it leads them back to the war torn streets of Los Angeles. They fight their way back into the LA Dollhouse, during which Ballard is killed, and Anthony and Priya re-establish their relationship. Topher has developed a pulse bomb that will send a wiping signal into the ionosphere, and sacrifices his life to set it off. Afterwards, Echo and Alpha are left unchanged, and DeWitt promises to lead the newly wiped Dolls through the new world, which, it is implied, will rebuild. Echo imprints herself with Ballard and goes to sleep in her pod, now that Rossum is finally defeated for good.
