Daredevils of the Red Circle (1939)

39013, an escaped convict, carries out his revenge on the man who put him in prison, by imprisoning Granville and impersonating him, with the aid of Granville's traitorous aides. When destroying all of Granville's holdings in order to ruin him, he burns down the Granville Amusement Center, which claims the life of the younger brother of one of three circus daredevils. The three daredevils then swear vengeance against 39013, and are hired by Granville to hunt him down, even though the impersonation is in effect. Brilliant plot, with the best chapter endings caught on film, especially one and eight, and one is probably the greatest of all, with Gene trying to outrace on motorcycle a torrent of water quickly filling up a tunnel. 12 chapters. In terms of serials, 10 out of 10.
