In flashbacks, Mrs. Beakley first meets Scrooge after being assigned by S.H.U.S.H. Director Ludwig Von Drake to track down a page from The Great Book of Castle Dunwyn. Together, they defeat chemist turned F.O.W.L. agent Black Heron and secure the page before she can use its formula for gummiberry juice to create super-soldiers. In the present, Black Heron returns to kidnap Beakley in an attempt to obtain the formula, so Scrooge embarks on a mission with Webby to rescue her.
