Frank Courtney discovers that he is heir to a shipping line and travels to Los Angeles to claim his inheritance. The current president of the line, Norman Bryan, has been embezzling from the company and rather lose this opportunity, decides not to have Frank arrive in LA. Traveling with Frank to LA is Bob Whitlock, a radio operator for the company, but also the inventor of a machine that can destroy enemy planes and ships from a distance. Bryan, along w/ his assistant Mason, try to obtain the plans for the machine. Aiding Frank and Bob is Irene Blaine, who is actually Frank's cousin, also trying to clear the charges of company embezzlement against her father. For 12 chapters our trio, also with the help of Pal, the wolf dog, try to survive Bryan's plans of conquest. Average serial for Mascot, not aided by the fact that my print is missing pieces of footage and at least 8 cliffhangers, so its really hard to accurately judge the serial with the missing footage. However it is fun and moves at a quick pace with a lot of on location shooting rather than the Mascot lot. The cast seems to enjoy the serial, but the plot points such as Frank being abducted or Bob's invention being stolen are rehashed to death here. The serial's most memorable moment is probably Bryan's final scene in the serial. Rating, based on serials, 5.
