The title character in this inexpensive actioner was played by Ranger, one of the more palatable of the many Rin Tin Tin imitators of the 1920s. Ranger is cast as Grit, the faithful hound of human hero Larry (Sam Nelson). When Larry is framed on a murder charge, it is Grit who sets about to prove his master's innocence. The canine protagonist doggedly (ouch!) tracks down the genuine killer, who is so rattled by the experience that he topples off a cliff to his death. His job done, Grit is reunited with the exonerated Larry, who in turn finds female companionship in the form of heroine Babette (Virginia Bradford).
