Canadian Tom Merritt has discovered a substance, Compound X, that will cure infantile paralysis, which he extracts from a mine at Caribou, Canada. A country at war with Canada (unnamed because while Canada and the British Empire were at war with Germany, the USA "officially" wasn't in 1940) discovers that Compound X also contains magnetic properties which will make their mines effective against the British fleet, and dispatch one of their intelligence officers, John Kettler, to work undercover to ensure a steady stream of Compound X for the Fatherland. RCMP Major Ross King is killed in a fray against Kettler's henchmen, and his son, RCMP Sergeant Dave King continues on in his place in command of the Mountie post. The foreign agents open a "sham" sanitarium, supposedly to help paralysis victims, but actually to ship the gathered quantities of Compound X abroad to their warring country. Sergeant King discovers the fraud and exposes "Dr. Shelton", the sham head of the hospital. The ... Written by Les Adams <>

Serial Review
23 August 2007 | by (United States) – See all my reviews

Released in September 1940,this was the first of two serials starring Allan "Rocky" Lane as Sgt. Dave King of the Royal Mounted. A foreign nation has found that " compound X " being mined in Canada and used as a cure for polio can also be used to make magnetic mines to destroy Allied ships. Soon enemy agents are sent to Canada to supply that country with enough compound X for their war effort. This serial benefits from a strong cast headed by Allan Lane and Robert Kellard as Mounties out to stop the agents. Robert Strange as Kettler and Harry Cording as Wade Garson play the enemy agents. An equally strong supporting cast along with a literate screenplay,keeps the plot believable.Directors William Witney and John English never permit the action to drag . Top drawer stunting headed by David Sharpe, a memorable score by Cy Feuer, sfx by the Lydeckers and great location photography by William Nobles all add up to 12 chapters of stirring action !On tape and an excellent DVD produced by VCI. Highly recommended !
