The "red foam" of the title refers to the angry passion of revenge -- a typically poetic silent era touch. A girl (Zena Keefe) is tricked into marrying Andy Freeman (Harry Tighe) when he and her sister tell her that the man she loves, Arnold Driscoll (Huntley Gordon), has married someone else. Driscoll, believing that the girl no longer loves him, leaves town and goes to Buckeye Bridge where he takes over an abandoned quarry. Freeman realizes that his wife still loves Driscoll and it drives him wild. In order to exact revenge, he takes his wife to Buckeye Bridge and rents a house near the quarry. The girl is miserable when she discovers that Driscoll is still single, while she is stuck with a man she doesn't love. Freeman proves to be even nastier when he has an affair with Mrs. Murphy (Peggy Worth). The woman's husband (Johnny Butler) kills Freeman, but the evidence points to Driscoll. Driscoll is finally able to prove his innocence and he is reunited with his now-widowed sweetheart.
