MacGyver and the team attempt to rescue Sarah, Jack’s former CIA partner/ex-girlfriend who went missing in Venezuela after she obtained evidence to take down an international arms dealer.

Using a screwdriver and bug spray, MacGyver must find the U.S. government mole who is leaking classified intel to the organization that is trying to take down The Phoenix Foundation. Also, Sarah returns to help with the mission, and Nikki reappears, but Mac can’t tell which side she’s on.
