2nd gen Ran Tin Tin and Rex in the same serial! As the human hero they hire Bob Custer, a regular in westerns doing his best to handle the two animals. What is interesting is that his comic sidekick is actually billed OVER the hero in this production. The reason for that is that it's none other then BEN TURPIN!!! The cross-eyes man! So an fairly interesting cast and idea, but execution was kind of dull. They never managed to insert much excitement and the cliffhanger action wasn't that great.
