The characters starts to have sex. The kiss passionatley and starts to undress. Nothing much is shown (only bare male upperbody and female legs, some clevage).

One scene features some burning and gore.

The Girl smokes a cigarette in two scenes.

The Girl takes a drink on a few occations and offer The Caller one on one occation, but he refuses.

The characters share a glass of champagne together.

The whole setting is very intense and you never know what is happening next.

The end is pretty graphic looking and can shock and disturb most viewers.
