When high school students start dying from accidents related to "powerballs," a combination of anabolic steroids and methamphetamines, Walker hits the classroom as a substitute teacher in order to try to uncover the source of the drugs and stop the deaths.

Nate (Peter Krause), David (Michael C. Hall) and Brenda (Rachel Griffiths) take an interesting trip to Vegas for a funeral directors' conference; a baby's death from SIDS stuns the family; and Ruth (Frances Conroy) takes a floral-arrangement class.

The Sliders arrive at Oakwood Institute, which appears to be a sort of mental hospital. The patients are roaming the grounds without supervision, and one of them, a man who plays a violin without strings (Paul Sand), says they're having a riot. Maggie (Kari Wuhrer) and Rembrandt (Cleavant Derricks) decide to look around. Suddenly police cars pull up and helmeted officers order the patients to return to their rooms. Everyone begins running toward the building. Diana (Tembi Locke) and Mallory (Robert Floyd), unsure of what to do, follow along. Rembrandt and Maggie see a sign on the front gate identifying the place as a neural remapping institute. Not sure what it means, but certain it can't be good, they slip through the gate as it begins to close.
