When a musician and her husband move to a remote house in Wales, the music they make disturbs local ancient folk magic, bringing a nameless child to their door who is intent on infiltrating their lives.
The Mannequin follows Liana Rojas (Gomez), a creatively starved stylist assistant who discovers the historical downtown Los Angeles building where her sister mysteriously died is haunted by a serial killer who brutally murdered and dismembered his victims there half a century earlier. This forces Liana and her friends to find a way to free themselves and escape the sinister ghost before they lose their own body parts.
