When Mona's phone is suddenly activated, Caleb tracks it to a nearby storage locker. When he and Spencer break in, they discover that things are being kept bagged and separated as if preserving evidence. Could this be Holbrook's work, A's new lair, or both? In the back of the locker they find a foul smelling barrel that is preserving something, most likely a corpse. They think Mona's body might be in there, but have to leave before they can check.

Meanwhile, Aria is sent on a goose chase around town thinking that she is meeting up with Holbrook. She ends up having lunch with Jason who is also coincidentally stood up by Ashley. Afterward she is led to a florist and then to Hanna's house. The flowers are meant to out Ashley and Jason, but Ashley might do that all on her own now that she has all but rejected Pastor Ted's proposal.

Aria is being haunted by the letter she wrote. She tries to tell Ezra, but doesn't go through with it. Meanwhile, Emily's bossy new coworker encourages her to move on from Paige.
