One Day on AllMovie

One Day originated as the sequel to Elinor Glyn's steamy best-seller Three Weeks (itself filmed in 1915 and 1922). The action takes place some twenty years after the original novel, as Opal (Jeanne Iver), daughter of the man who "ruined" the Queen of Veseria and stole her throne, falls in love with deposed Veserian king Paul (Victor Sutherland). Alas, Opal is promised in marriage to a decadent but very wealthy nobleman. Hoping to escape this fate, she heads to France, where she is reunited with Paul during a driving rainstorm. Forced to take shelter in a hunting lodge, the two enjoy a hot-and-heavy romantic rendezvous right out of Mayerling. Fortunately for all concerns, her evil father is toppled from the Veserian throne, paving the way for a royal wedding between Opal and Paul.
