Matthew and Reginald Crosby, two brothers, and their cousin, James Thedford, manage an industrial conglomerate. Reginald marries an actress and gives so many lavish and ostentatious parties that one of them leads to a strike after being reported by labor editor Oscar Lackett. The strike leaders are fiery orator Jem Burress, German immigrant Louis Stolbeck, and Stolbeck's feisty daughter Louise, who is also Jem's girlfriend. John Stedman, a labor lawyer, lends moderation to the cause and thus impresses Matthew and Reginald's sister, Grace Crosby, who joins the workers. When Jem, jealous of Louise's infatuation with John, attempts to discredit him with the union members, Louise goes to John's apartment to warn him, but Grace arrives at the same time to accept John's marriage proposal. To prove her devotion to John and the cause, Grace summons her brothers to John's apartment, and when everyone converges, they finally resolve the strike.
