Butler is first framed with a prostitute and then apparently is guilty of killing Regan, though no bullet is found. A corrupt judge puts him away anyway. Butler is exonerated with the help of his secretary Ellen (Evelyn Knapp) after more corrupt figures are gunned down by a scientist called Volkov (Mischa Auer) with ice bullets.
Low budget and breezy but an entertaining film. There isn't a huge amount of depth, the corruption and the reaction to it being painted rather too broadly but Foster and Knapp make a nice pairing.
