The number one spy "Bat", who was designed by Lin Yayan and fell into the hands of Interpol, betrayed his adoptive father "Professor" to regain his freedom and became the new leader of "Ark".
Despite mutual suspicion, deception and betrayal, both of them honestly faced their growing feelings for each other and maintained an ambiguous relationship on and off.
Lin Yayan, who was curious about Pei Qufei's life experience, went to Italy alone at the instigation of the intelligence dealer "Hermes", but was unexpectedly set up by him and got involved in a dispute between the two sides for no reason. And his underground business in Italy seems to be under threat.
And Pei Qufei, who appeared in Italy at this moment, why did he come?
This time, will the two be allies fighting side by side, or will they become enemies again?
