Plot
Secret agent Boston Quackie embarks on a mission to deliver a crucial attaché case to the Slobovian consulate in West Slobovia, facing relentless attempts by spies to seize it. The pursuit unfolds aboard the Cloak & Dagger Express, where Quackie confronts a mysterious man with a green hat, suspected of theft.

Despite various encounters and a brief capture, Quackie ultimately outwits the thief with assistance from Mary and Inspector Faraway.
