Dog star Strongheart, perhaps the most popular rival of canine hero Rin-Tin-Tin, heads the cast of North Star. The "human" plot concerns wealthy young man Noel Blake (Ken Maynard), on the lam from the law after ostensibly murdering a man. Noel tries to start life over again, only to be victimized by blackmailer Dick Robbins (Stuart Holmes). A bit quicker on the uptake than the Authorities, Strongheart figures out that Robbins is the real murderer, and by film's end he has dragged the villain to justice. Syd Crossley and Jerry Mandy, two refugees from the Hal Roach comedy studios, do their best to steal the picture from Strongheart as a pair of slapstick hoboes.
