Five women compete in a slow motion race. They can only move while wetting and they're only allowed to pee when its their turn. In the meantime there's a lot of drinking beer and squirming while waiting around. Side contests, cosplay, general nudity and girls getting drunk - what more could you want in a gameshow?
