A tech billionaire hires Team Scorpion to rescue his kidnapped daughter. Meanwhile, some feelings get hurt when Walter gives an interview and fails to acknowledge the other members of the team.

Walter finally learns Cabe’s long-kept secret regarding the Baghdad mission, and it threatens to tear Team Scorpion apart forever. Also, Paige’s world is rocked when Ralph puts his life in danger to help the team.

Scorpion, torn apart and uncertain about their future as a team, must come together for their most important mission yet – to save Walter’s life as his car teeters on the side of a cliff.

Walter’s attempt to “normalize” goes horribly wrong when a nefarious virus is uploaded to his computer, turning Team Scorpion’s new “smart” building project into a burning death trap with people locked inside.

When Walter is accidentally launched into space in a rocket, he hallucinates about Paige as his oxygen runs low, and Team Scorpion works feverishly to find a way to bring him home before he suffocates.

While attending a tech convention, Team Scorpion is taken hostage by a group attempting a virtual heist.

On Christmas Eve, when Walter chooses work over spending quality time with his friends, he falls down the stairs and hits his head, and as he lays unconscious, he enters a dream world where Team Scorpion never existed.
