A scientist (mad of course) called Boroff (Bela Lugosi) has developed a disintegrating mist and wants to sell it to rival powers of the good old USA. Coast Guard Lieutenant Kent (Ralph Byrd) and his reporter girlfriend Jean (Maxine Doyle) gets involved with the hunt for the fugative Boroff and also has to tackle Boroff's brutal thug Thorg (Richard Alexander) who really makes this serial with his impressive and menacing physicality.
A succession of death defying cliff hangers to follow. This serial is well made though pretty familiar fare. Although Lugosi is the main villain, Thorg is the most memorable one. The rest of the cast do a competent though unexceptional job though this is well worth a watch.
