Gene Wilder plays Mr. Stein, the long-absent senior partner of Will's firm, who shows up unexpectedly to reassume command. He just might succeed if he weren't such a frantic, neurotic mess. What he needs is a smart, attentive lieutenant who can make decisions and do some of the dirty work (like firing people). Enter Will. Meanwhile, Grace and Jack are shocked to discover that their highfalutin' pal Karen is now poorer than a church mouse and living in her limo.

Will is up for partner at his law firm. His boss, Margot, invites the candidates for partner to a dinner at her house, where she will ultimately make the final decision. Will, who is worried that Vince will ruin his chances of getting the promotion, is reluctant to bring him as his date. Grace also attends Margot's dinner party under the pretense that Margot has set her up on a blind date. Once there, Grace realizes the blind date is with Margot's husband. Elsewhere, Rosario becomes sick and Karen refuses to believe she is really ill.
