Falling Skies — Season 1

Tom is named a commander of a regiment of citizen soldiers in the aftermath of an attack by aliens, whose purpose remains a mystery. Yet Tom's primary objective is to protect his three sons, one of whom is taken captive by the otherworldly invaders.

Tom leads the charge to gather more weapons at an armory, only to have a close encounter of the alien kind and come face-to-face with a band of dangerous renegades overseen by a magnetic leader named Pope.

A doctor (Steven Weber) who shares a history with Tom arrives at camp, and he may hold the key to saving the kids who've been abducted by aliens. Meanwhile, the ragtag crew has nightmarish encounters with skitters and mechs.

Tom and his crew undertake a mission to retrieve motorcycles and cautiously allow Pope to join them. While on the task, they're attacked by a harrowing entity that may be even more formidable than aliens. Elsewhere, Anne and Harris hit upon a crucial discovery.

Hal orchestrates a shadowy and perilous plan to slip into an alien lair to rescue Ben and other ensnared kids.

Another resistance leader appears at the camp, sounding an alert that the aliens will soon attack and offering to take the children to safe shelter. With time running out, Tom and the others must weigh his proposal.

Suspicions arise that danger may indeed lurk at the children's safe haven. Before long, Mike happens upon a harrowing truth and an unanticipated enemy emerges.

Weaver turns more and more erratic, stirring up trouble while on a reconnaissance mission with Tom and Hal. Meanwhile, Pope constructs a potent weapon; and Anne makes a startling discovery while performing an autopsy on a skitter cadaver.

Growing tension divides the 2nd Massachusetts just as their ambitious assault on an alien base draws near. Meanwhile, Tom has trouble coming to grips with Annie's profound discovery and its implications.

In the season finale, the resistance fighters launch a bold attack against the aliens as Tom remains at the camp to protect the civilians. Twisting developments lead Tom to a close encounter of the harrowing kind, and mysteries about the aliens' motives might finally be answered.
