While attempting to redefine her relationship with Riley, Buffy must also stop demons that are determined to reopen the Hellmouth.

Buffy teams with Riley after she is allowed access to the Initiative; Spike is targeted by commandos.

After joining forces with Adam, Spike drives a wedge between Buffy and her friends. Meanwhile, Angel's return to Sunnydale leads to a violent confrontation with Riley.

Having gained control of Riley's mind, Adam sets in motion his plot to create an army of unstoppable soldiers and destroy the Initiative.

Realizing they may never be able to vanquish Glory, Buffy and the gang decide to flee Sunnydale in Spike's R.V. to protect Dawn.

While trying to find a way to make Buffy forget about her afterlife experience, Willow inadvertently casts a spell that erases everyone's memories.

Buffy and her friends fear Spike may be to blame when a number of people around town mysteriously disappear.
