However, her happiness is threatened when Mark’s ex-wife, Julia, reenters the picture the moment she learns about the pregnancy. Initially, Julia’s actions seem benign—courteous and unobtrusive—but her behavior quickly becomes unsettling as she begins showing up uninvited and inserting herself into every aspect of Lila’s life. As Julia’s presence becomes more invasive and her motives more disturbing, Lila realizes she may be fighting to protect more than just her future—she may be defending her safety and sanity.
