Confiding in someone, Beth recounts a vivid nightmare that has profoundly affected her. We learn that, unlike other nightmares, this one has a clear grasp on reality and offers insight into what is lurking inside Beth's mind.

Nerdy accountant Harold and his irrepressible friend, Kumar, get stoned watching television and find themselves utterly bewitched by a commercial for White Castle. Convinced there must be one nearby, the two set out on a late-night odyssey that takes them deep into New Jersey. Somehow, the boys manage to run afoul of rednecks, cops and even a car-stealing Neil Patrick Harris before getting anywhere near their beloved sliders.
