The 2nd Mass picks up the pieces after a devastating alien attack leaves Maggie fighting for her life…and Hal fighting for Maggie. Meanwhile, Tom and Dingaan Botha (guest star Treva Etienne) are cut off from the rest of the group, buried under tons of rubble, where they must rely on an Enemy Ship to rescue them.

With the weight of humanity's survival on Tom and Lexi's shoulders, they must defeat Tom's mortal enemy and find a way to destroy the omnipotent Espheni Power Core. Meanwhile, a new, terrifying Espheni Bomb is dropped onto Chinatown – immobilizing the 2nd Mass and preparing them for Human Skitterizaton – in the season finale episode.

Tom and the remnants of the 2nd Mass learn to pilot a Beamer as part of their plan to destroy the Espheni Power Core, and the group draws straws to see who will embark on the dangerous mission. The threat of death hanging over everyone triggers long-simmering confrontations between many of our main characters, ultimately bringing the 2nd Mass closer together.

Kennex and Dorian investigate a string of murders by a copycat of a serial killer whom Kennex's father put in jail.

Meanwhile, CJ is trying to pull off a school dance that becomes a target for destruction by The Rooks after she unknowingly insults their leader.
