The Falling Skies trailer opens with scenes of a devastated city, with buildings in ruins and debris scattered everywhere. A voiceover explains that an alien invasion has taken place, leaving the world in chaos.

We’re introduced to Tom Mason (Noah Wyle), a former history professor who is now leading a group of survivors. The trailer shows Tom and his son Ben (Connor Jessup) navigating the post-apocalyptic landscape, trying to evade the alien invaders.

The aliens are depicted as large, menacing creatures with advanced technology. We see them attacking human settlements and abducting people, including children, using some kind of spinal implant.

Tom and the other survivors, including a group of fighters, are shown banding together to resist the alien occupation and try to take back their world. The trailer teases an epic struggle, with intense action sequences of the humans fighting against the technologically superior aliens.

The overall tone is one of desperation and determination, as the human characters fight for their survival in the face of an overwhelming alien threat. The trailer promises a gritty, high-stakes sci-fi drama exploring the human response to a devastating alien invasion.
