Juli Eng, in Los Angeles, learns from her grandfather, in Hong Kong, by telephone, that he has just bought a small fortune in diamonds. He dies of natural causes so, when Juli arrives for the reading of his will, she looks for the diamonds but they are nowhere to be found. She contacts her lawyer, Perry, in Los Angeles and is convinced they were stolen by Tudor Sherwin. In fact, the manager of her grandfather's Los Angeles office, Ralph Iverson, is the thief. Iverson is taking a ship back to the USA and partners with a professional thief and smuggler, Gilbert Terrell, to smuggle the diamonds into the United States. Juli is able to get on the same ship with Sherwin and Iverson at the last minute by taking a pilot boat to the ship after it had left the dock. U.S. Customs are on the lookout for Tyrell, thanks to a shipboard snoop and Perry, but they can find nothing when he arrives. When Iverson is literally stabbed in the back and found by Perry as Juli leaves Iverson's office, Juli is charged with murder and Perry defends her.
