In a grand hall of velvet and gold, an auctioneer presents the estate of a recently departed collector — a parade of macabre curiosities, each sold to the highest bidder. Then he arrives at the final lot: number 369, the one that was never in the catalog. Behind closed doors wait the wonders the collector kept closest — not the treasures he owned, but the ones he loved. As the bidding opens, we come to see what they're truly worth, and who was watching whom all along. The Estate Sale wears the skin of a horror story to tell a tender one: a homage to the great Guillermo, and to every misunderstood creature he taught us to love.
