Dan works at a bookstore in a deadly dull shopping mall where nothing ever happens. He hates his job. Rhoda has dragged her babysitting charge to the mall so she can meet her dealer and score some coke. Now the kid's run off, and she has two hours to find him. Rhoda bullies Dan into helping her search, but as they explore the neon-lit corridors behind the mall, disturbing text messages lure them into the bowels of the building, where old mannequins are stored in grave-like piles and raw sewage drips off the ceiling.
