Lots of intense scenes throughout: Unknown SUVs intimidate a cab with children by repeatedly crashing into it. A mysterious character chases the children through an underground 'forest' using an energy weapon and superhuman strength. A cab with children drives off the road and out of control down an embankment. An unknown threat with bright lights chases the cab through the dark. The cab almost crashes into the front of a train. An 'alien convention' includes some quick shots of people, some in scary looking costumes. Mysterious 'assassin' has a dark intimidating demeanour. The main characters are tied to tables in a lab where experimentation is discussed, but not visualized.
