Amazon adds critically acclaimed thriller Absentia to its lineup of original dramatic series--all episodes will debut exclusively on Prime Video in the U.S., as well as in select markets globally. Starring and executive produced by Castle's Stana Katic, Absentia centers on FBI agent Emily Byrne (Katic). While hunting one of Boston's most notorious serial killers, Agent Byrne disappears without a trace and is declared dead. Six years later, Emily is found in a cabin in the woods, barely alive, and with no memory of the years she was missing. Returning home to learn her husband has remarried and her son is being raised by another woman, she soon finds herself implicated in a new series of murders.
