Filmed by Fred J. Balshofer in 1918 as the anti-German war drama Over the Rhine, the project was reshaped and released in 1920 as An Adventuress—a cross-dressing caper set in the fictional republic of Alpania and headlined by female-impersonation star Julian Eltinge, with early appearances by Rudolph Valentino and Virginia Rappe. The film was later re-edited and reissued in 1922 as The Isle of Love.

A 1922 re-edit of Fred J. Balshofer’s earlier feature—shot in 1918 as Over the Rhine and released in 1920 as An Adventuress—this version was issued to capitalize on Rudolph Valentino’s sudden stardom. The cut boosts Valentino’s presence through repeated/enlarged shots, looping and out-takes, and reframes the story in a tropical island setting; it’s widely regarded as a cash-in reissue.

An old woman in Frederick, Maryland during the U.S. Civil War displays her American flag in defiance of the armies of Confederate general Thomas J. Jackson. Based on the folk tale that grew from the poem by John Greenleaf Whittier.

When Tom Drogan drunken, wild ways, cause his mother's death, his sister Nell swears to protect and reform him. On the pretext of paying back a gambling debt, Tom brings "Kid" Hogan to the house, but ends up shooting him in the forearm. Dan Hogan, Kid's brother who is a policeman, rushes to the scene and catches Tom running away. To avoid arrest, Tom tells Dan that he fired at Kid for molesting Nell, and in the face of scandal, Dan and Kid back down. As revenge, Kid enlists Mamie, his girlfriend, to force Nell into a compromising situation with a man on a street corner. Conveniently placed, Dan arrests Nell for solicitation, but Frank Roberts, her boyfriend, arrives and extricates her. When Tom hears of the plot, he confronts Kid in a dance hall and soon a raging gun battle breaks out in which Kid is killed. Badly wounded, Tom seeks refuge with Nell, who prepares to protect him with his gun. As the police break down her door, Tom dies.
