David and his friend Andrew lived in a big house together, kinda like a frat house, they always arranged parties, get togethers, drinking and smoking. They both went to Harvard University.

And earlier today, Andrew's younger sister came to visit him and she was going to stay there for two weeks. But she had no idea what she was walking into.

In the evening she came downstairs for yet another party, everyone were drinking and doing coke, David raised his head and he stared at her.
