Higgins summons Magnum back from a job in Detroit to help before T.C.'s sense of guilt knocks him out for good.

Magnum finds himself locked into a mystery when a bank teller accidentally traps the two of them in a time-release vault at Robin Master's bank. Inside, they find large amounts of counterfeit bills, which the teller believes is proof that her father, a world-famous painting forger, is back in business.

Love is truly blind when T.C. drags Magnum to a meeting with a gorgeous jazz singer, Alexis Carter, whom T.C. fell in love with years ago in Vietnam. Magnum warns that trouble follows Alexis wherever she goes, and sure enough, she reveals she's on the run from dangerous Detroit drug dealers.

St. Louis gumshoe Luther H. Gillis returns to Hawaii, accompanied by his secretary Blanche, to attend the annual Private Investigators convention, where Luther has been informed he will receive an award.
