Alma Rubens, at the time still a fresh face in motion pictures, starred in this Triangle melodrama. French artistJules Mardon (Francis MacDonald) travels to Italy for his health. There, he meets the breathtakingly beautiful Felice (Rubens), who is known as the Passion Flower. Mardon paints her portrait and she falls in love with him. But once he has finished the painting, he takes it and leaves, never to return. The painting is hung in a Paris salon, where it catches the attention of wealthy Armande de Gautier (Wheeler Oakman). De Gautier becomes determined to meet the Passion Flower and he travels to Italy and wins her love. They marry and are happy for several years, especially after the birth of their son. But then Mardon shows up and forces Felice to run away with him. De Gautier believes that she has deserted him and their child, and when she returns, he throws her out of the house. The boy has been stricken with the plague, and before she is forced to leave, Felice kisses the germ-infested child. Then she immediately returns to Mardon, feigns passion for him, and plants her plague-ridden lips on his. Mardon dies from the disease. Both Felice and her son survive, and she reconciles with her husband. ~ Janiss Garza, Rovi
