Plot
Rinty, the courageous dog of the desert, embarks on a thrilling journey from the wild sands to the heart of the bustling city. Rescued and given a home by June, granddaughter of Pop Marlow, the proprietor of a dime museum, Rinty quickly adapts from desert adventurer to skilled thief-tracker navigating the urban jungle. Pop Marlow grows suspicious and fires Mike Doyle, a ruthless animal trainer whose unwelcome attentions toward June cross the line. Soon after, Pop mysteriously vanishes. Concerned, June implores her sweetheart Pat, a steadfast police detective, to enlist Rinty's help in finding him. Rinty leads Pat through the shadows of the city's underworld to a sinister haunt where Pop is held captive by Doyle's gang. In a tense moment, Pat is attacked by the gang's fierce bulldog and, in the confusion of the darkened room, mistakes the bulldog for Rinty. At the police station, just as Rinty faces an unjust death sentence, Pop Marlow escapes his captors and arrives in the nick of time to save his loyal dog. Reunited, June, Rinty, and Pat look ahead to a hopeful and happy future. ==Cast==
