Dangerous Partners

Carola and Clyde Ballister find a briefcase containing four wills leaving $1-million bequests to an Albert Kingby. They visit the Cleveland home of the first person who wrote a will benefiting Kingsby, a man named Kempen. They meet his attorney, Jeff Caign, and learn Kempen intended to leave the money to a singer, Lili Roegan.

Kempen dies mysteriously, so the Ballisters take a train to go see Professor Ludlow, the next beneficiary. Caign tails them, discovers a dead Clyde, in Kingsby’s compartment and becomes the crooked Carola's new partner.

The real Kingby turns up. He apparently is part of a Nazi group assisting war criminals. Carola and Caign, now lovers, go to New York City, where they are taken captive by Kingsby and pressured to reveal where the missing wills are. The police close in, kill Kingby but don't charge Carola and Caign, who are free to get on with their sordid lives.
