Secret Mission - Undercover Agents Never Back Down!

Riko Ikazuchi is an undercover agent who keeps her true identity hidden while infiltrating different crime scenes. She is posing as a newlywed with her junior colleague Noma in an apartment where a criminal organization is based.

To apprehend a drug deal in progress, Riko Ikazuchi and her junior colleague Noma stake out from inside their car. A member of the criminal organization becomes aware of their presence and approaches the car.

Riko Ikazuchi is brought to the hideout of the criminal organization in a drugged state. When she awakens, she is informed by one of the organization's men that they had known about her undercover operation since long before.

Riko Ikazuchi, who had kept her feelings for her colleague Noma at bay, now finds herself uncertain about her emotions. Riko falsely claims that the lingering effects of the aphrodisiac given to her by the criminal organization are still affecting her, and she initiates an intimate encounter with him for the first time.

Riko Ikazuchi, in pursuit of the criminal organization, attempts to carry out an undercover investigation at a nightclub with Noma by her side. In a club filled with couples, Riko decides to take the lead with Noma.

Guided by a duo of drug dealers, Riko Ikazuchi enters the club's backstage with Noma. However, as soon as they enter the room, iron bars descend and trap them inside.

To make the lookout drug dealer open the iron bars, Riko Ikazuchi entices him into a threesome. The dealer, clearly excited, unlocks the door and pushes Riko down with enthusiasm.

Riko Ikazuchi reports to her superior with Noma. While preparing the report, they miss the last train and have to stay overnight at the headquarters. It's there that Noma asks Riko if it's true that she has a boyfriend.
