With the "inside" help of misguided maid Maria Montoya (
Pilar Seurat), a gang of thieves steals a 33-carat diamond from wealthy Everlyn Harcourt (
June Vincent). The FBI enters the scene after one of the crooks is killed during the heist and the rest scatter to the four winds. Athough the gang's fence is captured, master thief Victor Amazeen (
Jack Klugman) manages to elude a trap set by Inspector Erskine (Efrem Zimbalist Jr.)--but if Amazeen thinks his problems are over, he is sorely mistaken. Featured among the villains is future Hill St. Blues star Daniel J. Travanti, here billed as Dan Travanty. ~ Hal Erickson, All Movie Guide
