Cowboy Tom Gallagher, escaping from a saloon fight with Black Carter and Thug Peters, rescues Little Joey and his dog--who have been sent "parcel post" to Dorothy Manning's Bar M Ranch by her sister--from an approaching train. Tom completes the delivery and is hired by Dorothy as foreman. There he finds Carter and Peters, who have been rustling Dorothy's cattle and stealing right and left from the Bar M. Peters buys up the mortgage and then kidnaps Dorothy when Tom goes away to get the money to pay it off. Tom effects her rescue with the aid of Little Joey and Bendy Mulligan, a rheumatic old cowpuncher. The mortgage is paid off, and Bendy's accidental discovery of oil while taking a mud bath solves Dorothy's financial problems. Dorothy and Tom wed.
