Summary
A lone whistle ricochets through the cavernous basement of the Rainbow Club, where Harpo’s gumshoe Watson—top-hat askew, trumpet mouthpiece for a badge—sluices down a coal chute like a silent comet, scattering soot and propriety. Above, Zeppo’s champagne-slick playboy presides over a cabaret that throbs with illicit jazz, while Jobyna Ralston’s weary starlet rehearses a song of escape. Into this nocturne stalks Groucho’s celluloid Nosferatu: mustache waxed to dagger points, frock-coat blacker than a creditor’s heart, Chico’s grinning Neapolitan goon forever at his elbow promising "protection." The plot pirouettes from missing pearls to mistaken identities, each revelation detonated by Harpo’s harp-strung glances and pocketed bicycle horns. Gunfire becomes tap-dance; a courtroom morphs into a carnival. When the final iris closes, Groucho shuffles toward the vanishing sun, ball-and-chain clanking like a broken metronome, while Harpo—mute no more in the language of desire—claims the girl and the last shimmering chord of a muted trumpet.
Synopsis
Harpo played the hero, a detective named Watson who "made his entrance in a high hat, sliding down a coal chute into the basement". Groucho played an "old movie" villain, who "sported a long mustache and was clad in black", while Chico was probably his "chuckling [Italian] henchman". Zeppo portrayed a playboy who was the owner of a nightclub in which most of the action took place, including "a cabaret, [which allowed] the inclusion of a dance number". The final shot showed Groucho "in ball and chain, trudging slowly off into the gloaming". Harpo, in a rare moment of romantic glory, gets the girl in the end.
