In the district of Khlong Ruea Yao, a legend is told of a procession of a hundred spirits that appears on the night of Loy Krathong, capturing any who see it and making them a part of the parade for all eternity.

Akara, a high school boy with a special sixth sense who feels alienated from others, must rely on his older sister, Anyarin, after a mysterious event upends their family’s life. Fleeing from the spectral procession that has set its sights on Anyarin, they find refuge in an abandoned mansion haunted by five ghostly children—each bound to the house by a tragic past they cannot escape.

Within the haunted mansion, Akara and Anyarin soon realize that they are not only running from the ghostly parade but must also confront terrifying truths about the spirits that watch them—and the chilling secrets buried deep within the mansion’s walls. The love and bond between the siblings are tested as Akara is forced to choose: remain shackled to a past he cannot undo, or step forward into an uncertain future.

As the ghostly procession draws ever closer, Akara must decide—will he move forward, or become another lost soul in a never-ending parade?
