Hostile alien creatures attack people in violent, and gruesome ways.
An injured man begs for help; he twitches, his skin begins to bubble and swell, and spider-like creatures burst out of his face (blood and tissue spurt).
A large crab/spider creature is shot and it splatters, and many other similar creatures begin spraying strands of acidic web: One man's leg is wrapped with webbing, he screams and his leg bleeds. A man wrapped in webbing falls to the floor and many small spider-like creatures break out of his back (blood and matter are sprayed) One man is sprayed in the face with acidic webbing (he falls to the ground screaming and a large creature comes and devours him) A woman sprays a creature with flames the creature burns. Dead man is covered by many small spider-like creatures, which appear to be eating his body.
A man is bitten in the back of the head by a large flying creature, and it pecks at his head and pulls strands of tissue out the back of his head (we see a large pool of blood on the floor).
We see many buildings and overturned cars covered with webbing, we see people covered with webbing and hanging from walls of buildings, and we see a school bus with a person inside covered with webbing.
A man punches another man in the face a few times (we see him with a bloody face). A woman slaps a woman in the face trying to stop her from talking and scaring people.
A man runs into a mist trying to reach his car, and we see him disappear into the mist and hear him screaming.
A mist moves over a store, the building begins to shake, shelving and light fixtures fall onto the people inside and we see a few people with injuries after. We hear a loud storm blowing outside a house, lightning, thunder and a thick cloud moves over a lake, the power is knocked out, a family goes to their basement and a huge tree breaks through their front window (no one is harmed). Some aftermath of the event is shown.
A man checking out a generator disables it, the lights turn off, and he strikes his head on a door-jamb, trips and falls to the floor.
A man with a bloody nose and blood on his shirt runs in a panic through a street and into a store and tells people that another man was taken away by something in the mist.
A woman tells people to prepare to meet their maker and that God is a vengeful god.
A boy asks his father to promise not to let the monsters get him. A boy pleads with his father not to leave him.
A man talks (in jest) about a crashed spaceship with frozen aliens inside it being kept in a military installation near where he lives.
