From Elvis, to dog shows to zombies you won't want to miss a minute of the fun. By the end of the season, a break in Beckett's mother's murder case leaves Kate and Rick's secrets exposed. With a sniper on the loose and her life on the line once again, will it break Castle and Beckett apart or finally bring them together for good. From beginning to end you won't want to miss a moment.
