Don Winslow of the Coast Guard [Serial] (1943)

Synopsis
The 13-chapter Don Winslow of the Coast Guard was the second of two Universal serials based on the comic strip Don Winslow of the Navy. Don Terry returns as Don Winslow, who has been promoted to Commander in this effort. Also returning is mystery villain The Scorpion, once more working in cahoots with the Japanese. Winslow's mission is to prevent the Scorpion from severing vital supply lines to America's armed forces. The "gimmick" prop this time out is an underwater aircraft carrier! Of the supporting cast, it's a bit surprising to see the exotically beautiful June Duprez acting in a serial, but she plays her nonsensical role with enthusiasm. ~ Hal Erickson, All Movie Guide
