The plot revolves around a sex slave who got disowned because he couldn't maintain an erection. It has a BDSM feel into it.

There's a graphic lesbian sex scene lasting for a minute.

A few of quite graphic violence. Not a lot, really.

Very little.

The film itself relies less on the plot and more on the atmosphere. It gets more intense in the second half of the film.

There's a sequence where a woman erratically walks around the subway and starts vomiting and regurgitating said vomit for 5 minutes.
