There is a somewhat lengthy sex scene in a shower stall. The woman's breasts can be seen occasionally. After about two minutes, we see the couple lying naked in a bed, although any potential nudity is covered up by blankets.

The plot revolves around an impending terrorist gas attack.

Men are shot on several occasions, with bloody results.

A naval base is attacked at the beginning. Men are killed in explosions and shot by silenced gunfire.

Two men are killed by an odourless gas released in the room. We see them convulse and foam at the mouths.

Standard R-rated language, with about twenty F-bombs and somewhat lenient use on milder words.

Some social drinking and smoking.

Nothing particularly frightening in this movie, although the ending can be a little intense.
