The beautiful and tough female agent Mallory (Genna Carano Gina Carano) has always been popular in killer companies, because no matter what kind of problem, it can always be perfectly solved in Mallory's hands. A week ago, after successfully rescuing the hostage Jiang from Barcelona, Mallory was urgently assigned to Dublin for another so-called "piece of cake" mission, but during the mission, she found that the hostage she saved from Barcelona had been killed in Dublin, and the evidence pointed to her. Mallory realized that she had been set up and was greeted by an international encirclement campaign. Forced to do nothing, Mallory had to run around with the help of several old friends, and had to protect her family in the United States before each other. What is more difficult is whether Mallory can find out who is behind it after she has pulled out on her own.
