I Love Eva Marsh
Summer 1996. A small town nestled in the shadow of a gigantic factory. Ben, a shy eleven year old boy, lives there alone with his mom when she leaves him to strike. The coming of the troubling Eva in his bunch disturbs him a little bit more, especially when she mentions the legend of a mysterious creature hidden under a nearby lake's pontoon. As a game, Eva challenges Ben: walk through the "pontoon of the death", and come back. But Ben fails miserably. At night, the Creature appears to him.
