In this reimagining of Alexandre Dumas's classic novel, the musketeer Aramis is secretly a woman in disguise, drawn to the elite corps after exacting revenge on her lover's murderer. Years later, plucky musketeer-in-waiting D'Artagnan is to be hanged for a crime he didn't commit. To exonerate her friend, Aramis must uncover the truth by navigating a twisting web of court conspiracies and her own past — without revealing her secret.

Researcher Mutsugoro takes his family to a remote and uninhabited island near Hokkaido, to study the local population of wild bears. Nearby poachers make his life difficult, and he "inherits" an orphaned bear cub, whom the family call Donbe and raise as one of their own.
