In the crystal clear lakes of Northern Wisconsin lurks a peculiar creature... the Chinese Mystery Snail which gets its namesake from female snails giving birth to young, fully developed snails that suddenly and ""mysteriously"" appear. Utilized for its high protein, low fat content in China, the mystery snail is a food source believed to aid in treatment of digestive disease. Eager to explore this feral snail as a food source, Yia travels to Clear Lake to meet up with Wisconsin Fisheries Specialist Titus Seilheimer, who's seen first hand the explosion of these snails at his family's lakefront resort.
