Matty reveals a shocking secret to the team: she has a husband who’s been undercover in a criminal organization called S-Company for eight years. When his status as a CIA agent comes out, Matty needs MacGyver to find and extract her husband before it’s too late.

When MacGyver takes Riley and Bozer into the wilderness for a weekend of survival training, things take a turn when they run into a violent group of criminals who are searching the rugged backcountry for a lost crate of money. Also, Jack and Matty go on a road trip to place Matty’s ex-husband and his family in witness protection.

Matty’s ex-husband, Ethan, asks her for help when a criminal organization, S-Company, kidnaps his wife and daughter, forcing Matty to decide if she’s willing to commit treason in order to help him save his family. Also, Riley joins Billy Colton and Mama Colton on a mission to Paris and makes a heartbreaking discovery.
