Buffy and Dawn clear the house of magic items to help Willow and Buffy has a surprise visit from a social worker checking on Dawn's home life. The meeting doesn't go well and in a fit of rage afterwards, Buffy cuts off her hair.
Meanwhile, the Geek Trio have built an invisibility ray and accidentally hit Buffy with it, who takes advantage of her new situation by paying Spike a visit and messing with (deserving) people. Willow is really trying to stay away from magic but Xander confronts her, assuming she has cast an invisibility spell on Buffy, leaving her even more upset.
The Trio realise that the invisible objects are rapidly breaking down structurally and they kidnap Willow to force Buffy into the open. Buffy and the Geeks have an invisible fight in an arcade until Willow returns them to normal and Buffy finally discovers who they are, before they make a hasty (and rather geeky) escape.
