The story of Wingless Angel revolves around Kate Mercer, a highly skilled F-15E fighter pilot in the U.S. Air Force, codenamed Valkyrie. During a high-risk mission over Syria, she violated operational procedures to save her wingman from a surface-to-air missile attack, sacrificing her own aircraft in the process. A military hearing determined her actions were reckless, permanently revoking her flying license and stripping her of the career and identity she had dedicated her life to.
