Premise evokes an environment in which acts of compassion and mercy usually end in infection and death. Much is made of brotherly loyalty and sibling love (real-life brothers created this movie). But none of it proves strong enough to overcome the selfish, life-or-death choices here forced by a deadly virus.

Fatal and non-fatal shootings draw blood, including the death of a dog. Gruesome corpses, as characters infected with the disease bleed and die, and one is shown after being burned on a pyre.

Suggestive talk ("eat me") between boyfriend and girlfriend. They start to strip for sex but get interrupted. A band of male survivors threaten to take the leading ladies, for their own unstated (but easy to guess) purposes, make them strip to their underwear for inspection.

Use of the s-word in varied permutations, "ass," "piss," "S.O.B." A written racial slur. One utterance of the F-word.

Car models, Jack Daniels whiskey on display. Mention of SpongeBob Squarepants.

Mention of "weed" (chiefly its absence). Drinking of beer and liquor until drunkenness sets in.
