Patrolman Killegren, seated alone in his home, is startled by the sound of shooting. Rushing outside, he meets several officers who inform him that two thieves, attempting to escape, had entered his cottage. Positive that no one had entered the house, Killegren conducts the policemen through the building. The father is startled, upon entering his son Alex's room, to find the boy at home. Knowing that his son could not have been in the room more than five minutes, Killegren is filled with a terrible suspicion. After the officers have departed, the father returns to Alex's room. He finds the boy unconscious. Reviving, Alex tells of how he had been duped by Marcia Judson, an adventuress, into helping her rob a ruby from Duare, a collector of gems. Innocent of the part he was playing, the boy aided her to escape from the police by hiding her in his room. Danger of capture over, Marcia emerged from her hiding place and jeeringly informed Alex of how he had been victimized. He attempted to snatch the jewel from her grasp, but a blow from behind knocked him senseless. The following morning, Killegren, debating whether to place his son under arrest, learns that the ruby has been recovered. It seems that Duare's Hindu servant had trailed Alex and Marica and overheard the conversation which took place in the boy's room. Seeing Alex attempt to seize the gem, the Hindu, mistaking his motive, climbed through the window and laid him low. The man then compelled Marcia to surrender the ruby. He was taking her to the police station when the woman broke from his grasp and escaped. Delighted at the turn of events, Killegren arranges for his son's exoneration.
