The film revolves around Chastain, Nyong'o, Cruz and Fan, who play spies from international agencies around the world. These women must bond together, overcoming their suspicions and conflicts, to use all their talents and training to stop an event from occurring that could push the world into chaos.
Along the way, these strangers and enemies become comrades and friends, and a new faction is formed - code-named '355' (a name they adopt from the first female spy in the American Revolution).
Chastain along with Kelly Carmichael for Chastain's Freckle Films and Kinberg for his Genre Films is bankrolling the film. It is executive produced by Richard Hewitt.
The idea of this film was proposed by Chastain while she was working with Kinberg on the latest X-Men movie 'Dark Phoenix'.
However, the film suffered a major setback when a whistleblower accused Bingbing of tax evasion. She then stepped out of the limelight in her home country China and admitted to wrongdoing on social media.
'355' will mark her first big-screen role post the scandal.
