After losing her husband and daughter in a car accident involving Amy Martin, Catherine falls into a deep depression and blames Amy for the tragedy. She begins stalking Amy’s husband Liam and daughter Corinne and applies for a job as Corinne’s live-in nurse under the name Victoria Jones. Catherine uses a fake identity as a former patient named Eleanor to secure the job and sets her sights on replacing her lost family with Liam and Corinne. She wins them over with her charming personality and she even wears Amy’s dresses. She poisons Corinne’s tea in an attempt to get closer to Liam, but his co-worker Beverly drinks the poisoned tea and confronts Catherine. Catherine drugs Beverly and tries to drive a wedge between Liam and his mother-in-law by planting a pamphlet about child custody. Liam becomes suspicious of Victoria when he realizes that she is not from the agency that sent the other applicants.
