Complete story — includes the ending
Castle is called in to negotiate a hostage crisis involving a murder suspect who will only speak to him, and puts his life in danger when he exchanges himself for two of the hostages. Castle believes she is innocent and discovers she was framed for murder. Gates allows Beckett, fired from her federal job after what happened in the last episode, to assist with the investigation, even though budget cuts have prevented her reinstatement to the precinct. With the case resolved upon the real culprit being apprehended, Beckett is returned to active duty thanks to the support of an influential man met during the investigation who turned out to be the long-lost biological father of the murder suspect.
