The Replacement

Ellen gets pregnant soon after landing a big contract for her architectural firm, and she hires Paula to fill in for her. But soon she thinks she"s made a terrible mistake. Ellen wants to get back to work, but Paula has other ideas. She wastes no time in moving in on Ellen"s bosses, clients, and friends, and Ellen fears she"s being forced out.

Ellen tries to juggle her attention to her baby with her return to work and her investigation into Paula. She finds evidence that her boss was having an affair, but her only leads are Paula"s 10-year-old child and a former colleague of Paula"s, neither of whom wants to speak to her. Paula discovers Ellen"s investigation and causes a scene with a client and a warning visit from social services.

After Paula confesses her secret, Ellen thinks she has proof that Paula is disturbed, but no one else sees it her way. The office turns against Ellen and she is forced to leave. She tries to put Paula behind her, but Paula isn"t willing to let go. When Ellen encounters Paula"s mysterious ex-colleague at an interview, Paula retaliates by driving a wedge between Ellen and her husband.
