Parents guide

There is a brief, violent sex scene; the woman's breasts are fondled through her bra and cunnilingus is implied (under a blanket), but there is no nudity.

A woman in a short slip sits on a dressing table and touches herself between her legs; again, no nudity.

Two women kiss, but it's part of a scheme rather than a sex scene.

A woman removes her dress, exposing her panties and (briefly) bare breasts.

Several characters are stabbed, others are shot, one is hit with a bottle and the broken glass used to gash his throat, another is set alight.

One sex scene borders on rape.

There is an attempted strangulation.

A dog is butchered.

Increasingly strong swearing as the violence intensifies.

The characters are on a pleasure trip, so there are several scenes involving alcohol. An actor is shown drinking from a 70cl bottle.

One character is sedated.

This is a supernatural thriller in which violent murder is a key element of the plot. It also takes place within the claustrophobic confines of a pleasure yacht.

Blood is shown on the deck, and in one case smeared across both a wall and a bedspread.
