Fran's lost her key, and she is around the back of her building seeing is she can get back into her flat without one. She has a second more pressing problem - she's right desperate, and before she can get her denim jeans down, it starts flooding through them! Her legs get soaked, the stairs get soaked, she eventually gets them down, and lets out so much pee you can see why she had to go. Now how will she get back inside?
