DAREDEVILS OF THE RED CIRCLE
Daredevils of the Red Circle (1939)
A 12-Chapter Republic Movie Serial starring Charles Quigley, David Sharpe, Herman Brix (better known under his subsequent stage name, Bruce Bennett) and Charles Middleton. It was directed by William Witney and John English and is often considered one of the better serials produced by Republic.
An escaped criminal, known as Harry Crowl, but preferring to be called by his prison number 39013, seeks revenge on the man who sent him to prison, millionaire philanthropist Horace Granville. He kidnaps Granville, imprisoning him within his own house, and disguises himself to take Granville's place. He then sets about methodically destroying everything Granville owns.
Setting his sights on the Granville Amusement Centre, at which a trio of acrobats is performing, the daredevils, Gene, Bert, and Tiny escape but Gene's kid brother is badly wounded in the blaze, and later dies of his injuries. Seeking revenge they take jobs as private investigators for the man they believe to be Horace Granville. Through a series of deadly traps, and with the help of a mysterious cloaked figure, known only as "The Red Circle", the daredevils begin to unravel the truth.
