A team of elite members have been selected for a top secret mission to save the earth. 

On June 24, SF9 unveiled a comeback film for 'Project OF9'. The film begins with agent Inseong observing dangerous occurrences across the globe from a hidden office. Inseong then provides a briefing on the situation, explaining that he and Youngbin will be away conducting research on the natural disasters around the world. Agent Rowoon, on the other hand, has been assigned to a rescue team in Seoul. 

Inseong then calls on an elite team of members to embark on an undercover mission, including agents Dawon, Zuho, Taeyang, Hwiyoung, and Chani, for the mysterious 'Project O9'. 

What do you think of the unique concept for SF9's summer comeback? More details on 'Project OF9' will be revealed soon!
