chunk: Manhattan press agent Sidney Falco (Tony Curtis) has been unable to gain mentions for his clients in J.J. Hunsecker's (Burt Lancaster) influential, nationally syndicated newspaper column of late because of Falco's failure to make good on a promise to break up the romance between Hunsecker's younger sister Susan (Susan Harrison) and musician Steve Dallas (Martin Milner), an up-and-coming jazz guitarist.
  Falco is losing money and clients. Given one last chance by the bullying, intimidating Hunsecker, he schemes to plant a false rumor in a rival column that Dallas is a dope-smoking Communist, then encourages Hunsecker to rescue Dallas's reputation, certain that the headstrong boyfriend will reject Hunsecker's favor and end up looking bad to Susan.
