Claire loves Halloween and is gearing up to spookify the Dunphy house for the trick or treaters. She gives each family member a role to play, but none of it goes quite right... Cameron can't shake a traumatic childhood experience and hates the holiday, Mitchell has had a terrible day at work, and Gloria is acting weird after Jay and Manny teased her about her accent.

The Thanksgiving holiday is more difficult for the interns and residents than any of them is willing to admit, as Izzie plans a big dinner at Meredith's -- but it remains to be seen who among the invited guests will actually show up. Meanwhile, George endures the O'Malley tradition of hunting turkeys with his less-than-sophisticated family, and Meredith treats a patient who's been in a vegetative state for 16 years.

The BAU team heads to Portland, Ore., to investigate a chilling abduction that may be linked to a local couple who were killed in their home a week earlier.

The investigation into the death of a contestant on a popular dance competition show leads Castle and Beckett to a shocking secret that may have led to her death.

It’s Halloween time at The Jeffersonian as the team gets a surprise visit from Lt. Abbie Mills and Ichabod Crane, who have traveled from the spooky town of Sleepy Hollow to help on a murder case of a young woman whose body is found on top of a 18th century military general’s headless body. The new foursome must figure out how to work together to discover who the 200-year-old headless corpse is and how the two murders are linked. Meanwhile, Booth and Brennan come up with the ultimate Halloween pranks to play on each other in the special.
