The West Jefferson Mall, once bustling with activity, is now shuttered and slated for demolition. Years ago, it was the scene of a horrific murder-suicide, making it an ideal spot for an outrageous Halloween bash. Spanning two levels and fifty thousand square feet, the party is filled with thumping music, alcohol, and alluring costumes. However, an unexpected guest crashes the festivities. As the night unfolds, only one woman with psychic powers survives, finding herself in a deadly game of cat and mouse with the killer. She navigates through the mall, using her abilities to piece together the last movements of the other partygoers.
