Episode Summary via en.wikipedia.org:
Irisa has another vision in which she sees Sukar killed by an object falling from the sky; she and Nolan seek out the Spirit Riders to investigate. Her vision is confirmed and they determine that the object was part of a storm of “razor rain” - small Arkfall objects - approaching Defiance. Nolan returns to warn the town while Irisa attends Sukar’s “sinking” ritual, where his remains will be consumed in an acid bath. Sukar rises fully healed from the bath, throwing the Spirit Riders into confusion; he and Irisa return to Defiance where he starts to collect numerous objects for an unknown purpose. Nicky arrives at the McCawley home, looking for Birch; Quentin admits to Rafe that he killed Birch but does not tell him he kept the artifact. Nicky tricks Rafe into admitting he killed Birch, knowing that he would do so quickly to cover for a member of his family. Luke appears to Quentin and suggests that Quentin kill Nicky, but he refuses. Stahma attempts to hire Kenya to “initiate” Alak sexually before his marriage to Christie; Kenya politely refuses and the two have a conversation over drinks which ends in a lesbian encounter. Alak and Christie have an argument over a proposed bathing ceremony in relation to the marriage; he agrees to approach his parents and cancel it. Sukar and Irisa take over the radio station and broadcast a message at a falling Ark; Nolan attempts to stop them, shooting Sukar and throwing him from the Gateway Arch. Irisa broadcasts the message, enabling the Ark engines which changes the course of the falling object and saves Defiance. Sukar’s miraculous healing is revealed to have been the result of nanites injected by the razor rain object which initially killed him; he survives the fall from the Arch but is paralyzed.
