In the new season, the protagonists still go around the world to perform secret missions, while their wives silently support them in the rear and keep secrets for their husbands. Their adventures continue. This time, when the secret operation team went to Pakistan to perform a mission, a key member stayed behind and planned to leave Fort Griffith and his operation team permanently. Mack and Tiffy are uneasily planning a new life after leaving the operation team, while Mark's former teammates are struggling in the wild. After successfully completing the mission of intercepting the package in Pakistan, the secret operation team must reorganize and focus on the second mission to prevent terrorists from spreading a deadly disease in the Western world. At the same time, Tiffy truly realized the impact of leaving the operation team when helping a student who suffered domestic violence, and hesitated whether he should really leave. On the other hand, Kim and Bob are welcoming new members to join... Their mission is still going on. New brothers and new partners need them to adapt and rely on. Please look forward to the second season of the secret operation team.
