How Could You, Caroline? (1918)

Caroline Rogers, a spirited young girl with a taste for highly romantic novels, comes home from boarding school to attend her sister Ethel's wedding. Having read a particularly lurid novel entitled Twin Souls recently, she arrives at the rehearsal wearing a daring gown in the hope of ensnaring a "soul mate." Because of his poetic name, Caroline becomes involved with Reginald Van Alden, a married fortune-seeker. On the morning of the wedding, she abandons her old sweetheart, Bob Worth, to take a ride with Reginald, but when he takes her to a disreputable roadhouse, she escapes and then tries to commit suicide by drinking cologne. Later she becomes engaged to Bob and attends his bachelor party disguised as a cabaret dancer. At the party, the two are married in a mock ceremony, but the next day Bob reveals that the friend who presided at the "wedding" is a real judge, and that he and Caroline are legally married.
