Harry Tasker is a first-class international spy for U.S. intelligence agency Omega Sector, and his wife, Helen, a language professor bored with her daily routine, makes the shocking discovery that her seemingly ordinary husband is leading an extraordinary double life. With the secret out, Omega recruits Helen, who impresses everyone with her formidable skills, and she joins Harry and his team of top-notch operatives, embarking on covert missions around the globe and an exhilarating life of danger and adventure - all while keeping their adventures a secret from their children. The renewed bond between them adds much-needed sizzle to the Taskers' emotionally distant marriage and upends the top-secret world of Omega Sector. But, as Harry says, if you're going to save the world, you might as well do it for the ones you love.
Helen gets her first official Omega Sector assignment – going undercover with Harry and the team at an academic conference in Madrid to stop a bioweapon terrorist attack. During the mission, Harry does his best to keep his history with Ximena, a sexy cryptographer they must work with to complete the mission, away from his wife.
The Omega Sector team must track down a dangerous hacker with missile codes that could cause war to break out in the middle east if they fall into the wrong hands. When the hacker turns out to be a moody teenager, Harry and Helen attempt to use their parenting techniques from home to get him to cooperate, which proves to be more challenging than handling the miscreants they usually deal with.
The entire Tasker family takes a trip to Mexico for Harry’s annual computer sales family retreat, which Helen learns has been an ongoing cover for his real job as a spy. The simple mission goes awry when a notorious spy hunter threatens to take out the entire computer sales retreat to capture Omega Sector spies while Dana and Jake are missing.
Despite Gib’s passionate arguments, Omega Sector requires the team to work with his estranged father, Al, when the weapons manufacturing plant he built gets taken over by a domestic terrorist organization with employees trapped inside. Harry and Helen must learn to work in sync like never before to neutralize the threat, rescue the hostages and survive the bickering between Gib and Al.
After a van full of computer software containing confidential information about Omega Sector operatives gets hijacked, the team enlists the help of Max, a teen hacker, to learn who is going after the agency. When Harry and Helen discover that Max is dating their daughter, Dana, their actions put the mission in jeopardy.
