Jim and Artie have only one clue to track down the smugglers of opium and Chinese aliens: a fortune cookie.

Jim meets with crime czar Sabatini, who asks him to travel to Calliope, MO to protect a lady and give a man called Swanson a key. Accompanied by government chemist Ned Brown, Jim travels to Calliope (where an Army finance officer died after stealing half a mil). Swanson is killed and the lady turns out to be Sabatini's ward blind Sylvia. It turns out Sabatini was the officer and Sylvia was the daughter of Boorman, Sabatini's partner in the robbery. Dodging Boorman, Jim and Ned find Sabatini's deed leaving all of his property to Sylvia.
