An opportunity presents itself when Park's valet resigns after his employer strikes at the man in a drunken rage. Ignorant of the fact that Rolfe is a millionaire, Park engages him. The sociologist learns that the clubman neglects and mistreats his wife, Evelyn. As time passes, Evelyn and Rolfe fall in love with each other but keep what is in their hearts, secret. On one of his nights off, the millionaire-valet visits his club. Park meets him, and struck by the likeness between the millionaire and the valet, becomes suspicious. The dissolute wretch pours his story into the ears of Georgette, an adventuress, who has ensnared him. The days which follow, find Park treating Evelyn more brutally than ever in an effort to provoke a protest from Rolfe. Shortly afterwards, the men again meet at the club. Intoxicated, the drunkard attempts to attack the millionaire, but friends intervene. Fearing for Evelyn's safety, Rolfe returns to the Park home. Park, accompanied by Georgette, returns home and again attacks his valet. Evelyn, who endeavors to separate the men, is halted by Georgette, who threatens her with a pistol. In her agitation, the adventuress presses the trigger. The shot misses Evelyn, striking Park and killing him. Police, summoned by the frantic wife, place Georgette under arrest.
