Treat 'Em Rough is a 1919 American silent Western film starring Tom Mix and directed by Lynn Reynolds, who also wrote the screenplay based upon a novel by Charles Alden Seltzer.

[2] Mix's stunt work in this film was so impressive that a Variety reviewer suggested that trick photography was involved.

[3] As described in a film publication,[4] daredevil cowboy Ned Ferguson (Mix) is hired by John Stafford (Curtis) to stop the cattle rustling plaguing his ranch.

On the way to the ranch Ned is bitten by a rattlesnake and is nursed by Mary Radford (Novak), who is writing a western novel.

Ranch foreman Dave Leviatt (Le Moyne) tells Ned that Mary's brother Ben (Paul) is behind the rustling.
