In this action-packed crime adventure, Helen Holmes plays adventuress Helen, who works with a gang of diamond smugglers. Their leader sends her off to a mine, which she visits with Holsted, son of the mine's owner. She steals some stones and hides them in a bouquet, then sends them off in a toy balloon to the gang's leader. He is supposed to have them delivered back to her when she has boarded a ship, but the deliveryman mistakenly gives them to the Holsted maid. Everyone is confused as to the whereabouts of the diamonds, so secret service man Hudson is brought into the picture. He becomes good friends with Helen, and when she finally finds the diamonds, she turns them over to him. Then together they capture the gang leader.
