 Racketeer Tony Gazotti is thankful that lawyer Jackson Dumont helps him beat a murder rap, but Dumont just does it for the thrill of it and refuses payment. Dumont s defense of mobsters causes his firm to disown him and his girlfriend Sue to leave him. But when young Tom Siddell, Sue s new boyfriend, is framed for a murder, she is the first to come asking for Dumont s help. Dumont uses Gazotti s information network and the help of new girlfriend Gertie Waxted to find that rival gangster Jim Grelliman is involved in the framing of Siddell. When Dumont sends Gertie to Grelliman s apartment in a bid to blow open the case, she is walking on thin ice.
