Mason and Davis, employed in a large jewel concern, both love their employer’s daughter, Helen. She prefers Mason, much to his rival’s disgust. On the night that Mason starts on his vacation a string of pearls is delivered to the jeweler, with the request that he place it in his safe. He carelessly drops the necklace into his ledger and places the empty box in the safe. Next day the pearls are missing, and Mason is suspected of the theft. He is arrested and brought back to town. Davis finds the pearls and carries them home, as he wants to incriminate Mason in Helen’s eyes. His sister, Edna, finds the necklace and, thinking it of no value, wears it to a dance. She loses it, and Davis almost goes insane for the pearls are priceless. Edna’s sweetheart rushes back to the ballroom and finds the necklace. Davis grasps it thankfully, and early next morning he is at the office and replaces it in the ledger, where he calls his employer’s attention to it. Mason is released at once, and as Davis sees Helen rush to her lover’s embrace he no longer feels the old jealousy, but just thankfulness that the pearls are secure in the safe.
