Twin Peaks

After Renault is killed in a shoot-out with police, and Cooper is cleared of the charges, his former FBI partner and mentor Windom Earle comes to Twin Peaks to play a deadly game of chess with Cooper, in which each piece of Cooper's that he takes means someone dies. As Cooper explains to Truman, during his early years with the FBI alongside Earle, Cooper had begun an affair with Earle's wife, Caroline, while she had been under his protection as a witness to a federal crime. Earle went mad and killed Caroline, tried to gut Cooper with a knife, and was subsequently committed to a mental institution. Now having escaped and come to Twin Peaks, Earle hides out in the woods so that he may go about plotting his revenge scheme.

As this is going on, Cooper continues to try to track down the origins and whereabouts of BOB, and learns more about the mysteries of the dark woods surrounding Twin Peaks. It is here he learns of the existence of the White Lodge and the Black Lodge, two mystical extra-dimensional realms whose gateways reside somewhere in the woods, and which are occupied by spirits that appear in Cooper's dreams and visions (metaphorically referred to as owls — "The owls are not what they seem"). Cooper also falls in love with a new girl in town, Annie Blackburn.

When Annie wins the Miss Twin Peaks contest, Windom Earle kidnaps her and takes her to the Black Lodge, which Cooper realizes has been Earle's goal all along. The Black Lodge then is revealed to be the place where BOB, the Little Man from Another Place, and the Giant come from, and where the red-curtained room of Cooper's dream is located. Cooper follows Earle into the Lodge, and has a set of bizarre encounters with doppelgangers of dead characters, including Caroline, Earle, and Laura and Leland Palmer.

During Cooper's journey, Windom Earle is apparently killed when his soul is consumed by an enraged BOB after Earle tries to claim Cooper's own soul in trade for Annie's life. Cooper then tries to escape, but cannot find the exit in the non-linear path of the Black Lodge. He is also chased by his own smiling doppelganger as he tries to find a way out. The Cooper doppelganger catches him, as BOB laughs. Cooper returns to the woods, with Annie by his side, both found unconscious on the ground by Truman. Some time later, Cooper awakens in his room at the Great Northern Hotel, and is tended to by Truman and Doc Hayward. He then requests to brush his teeth in his bathroom. Locking the door behind him, Cooper then smiles uncharacteristically as he pours toothpaste into the sink. He then slams his head into the mirror, and when Cooper's bloody face turns toward the camera, he laughs — we see his reflection is that of BOB. Apparently the Cooper doppelganger has exited the Black Lodge, thus taking the real Cooper's place. The series then ends on this cliffhanger.
