Mulder and Scully track a serial killer whose gruesome MO includes leaving many victims but few clues.

Brie Larvan aka the Bug-Eyed Bandit (returning guest star Emily Kinney) breaks out of jail and turns up at Palmer Tech threatening to kill everyone unless she gets the biochip that is implanted in Felicity's spine. When Oliver realizes that Felicity, Thea and Donna are trapped in Palmer Tech with everyone else, he looks to a surprising ally to help Team Arrow save the day.

When Team Arrow learns what Damien Darhk's devastating next move is, Felicity realizes she needs to ask her father, Noah Kuttler (Tom Amandes), for help. Noah and Oliver have a heart to heart talk that leaves Oliver rattled.

The two police officers who witnessed the spaceship landing during the meteor shower take Lex and Lana hostage and threaten to kill them unless Lex reveals where he hid the spaceship. While escaping to a "panic room" in the mansion, Lex is hit by a bullet meant for Lana. Fearing Lex may bleed to death, Lana asks him to tell the officers the secret location, but he confesses the ship has been missing for weeks. Meanwhile, Clark discovers that Lana has been researching the spaceship with Lex and fears she is close to discovering his secret.
