The Marins take in Alison while her father is out of town, leading Hanna to drink more heavily. Meanwhile, Aria proves to be a neglectful maid of honor to her mother; and Spencer and Emily attempt to identify the dead girl in Alison's grave.

Ali may hurt an innocent man and walk into A's trap if she lies about who abducted her, so Emily tries to persuade her to do the right thing while Spencer devises a backup plan. Elsewhere, Hanna attempts to lead a more ordinary life.
