Cassies Stuart leads the uncooperative Charles Dance into a world of misplaces government secrets, capalistic artists and bungling secret agents. Will the truth be out, or will the attempts of agents suppress the truth hidden within government propaganda films, classified as top secret by complete mistake, be successful. Or is it the mysterious medical records that are the true catch of the spies.
Unfortunately the movie Hidden City is not yet available on HBO Max.
