Though happily married, Simon falls for Clair’s seductive wiles and then, in the middle of the trial and the torrid affair, discovers that Clair is guilty. Simon’s associate, Lane, finds incriminating evidence against Clair. Simon tries to end the affair. But Clair cleverly sets up Lane so that when Clair kills Simon, Simon’s wife suspects Lane — and shoots her. Clair Archer is judged “not guilty” and walks away free.
