Joan Bennett is a manicurist who becomes a newspaper reporter. She joins forces with jaunty detective Cary Grant to get the goods on a particularly vicious insurance racket. Bennett unwittingly puts her life in danger by dating a supposedly above-board socialite (Walter Pidgeon) who is actually the brains behind the criminal operation. Big Brown Eyes is an enigma; every time we think we're in for a screwball comedy, something awful happens to jolt us back to reality. It's hard to lightly dismiss such scenes as the shooting death of a baby in its stroller.
