Western
A Johnny Mack Brown western from Supreme Pictures, one of the smallest of the poverty-row studios. Brown plays Billy Donovan, a drifter who rides into a valley looking for the man who murdered his sister and hires on at the Halloran ranch, where a masked night rider the locals call the Phantom has been picking off anyone who gets too close to a stolen fortune. Directed by S. Roy Luby, who cut his teeth editing B-westerns before moving into the director's chair. The phantom-rider gimmick gives it a whiff of the era's "weird western" cycle — more mystery than shootout. The film entered the public domain after its copyright was not renewed.

Western
A Johnny Mack Brown western from Supreme Pictures. Government agent Dan Doran rides into a lawless territory to break up a gang that has been running off homesteaders and rustling stock, but is himself framed for a stagecoach robbery by the real outlaw chief, Lige Branscomb. Posing as an outlaw to infiltrate the gang, Doran has to clear his name from inside the hideout — with the help of Stella (Lois January), who knows more about the operation than she lets on. Directed by S. Roy Luby, a veteran cutter who became one of Poverty Row's most reliable western directors. The film's copyright was not renewed; it is in the public domain in the United States.
