The CSI team investigates the murder of a man suffering from a congenital hypertrichosis, causing him to grow excessive body hair. Elements of the case suggest a connection with a belief in werewolves. The case leads to the victim's sister, who suffers from the same disease. Because of her condition, she'd been hiding from the world, but it turns out that she's hiding facts that are vital to solving the case.
Michael takes the entire Dunder-Mifflin staff on a motivational cruise aboard a party boat on Lake Wallenpaupack, but his planned presentation is bogged down by numerous distractions, including a dance contest, limbo, snorkel shots, and the pushy Captain Jack. Also, Jim and Katy's relationship hits the rocks as Roy and Pam finally set a wedding date, which does more than disappoint Jim, and by the end of the night, Michael's motivational cruise doesn't go completely to waste when he shares a heart-to-heart with one of the workers.
