Deep river valleys, tall limestone bluffs sawing through the sky… thousands of years ago, this unique portion of the Midwest escaped the crushing effects of the giant Ice Age glaciers. But with its scenic beauty, this preserved primal landscape also conceals unimaginable terrors: Mississippi river cults, inescapable addictions, lives not lived and blood-thirsty vengeance from beyond the grave. Four terrifying tales of the macabre Midwest.

Set in the backwoods of rural Iowa, this is Regan and Addisyn's last summer after high school. Growing up next door to each other, the girls are as close as sisters. The two of them spend their summer detasseling corn at a local farm. Addisyn can't wait to leave their small hometown for college, while Regan has second thoughts. In between work, Addisyn is forced to manage her mother's recovery from opioid addiction while taking care of her little sister. Regan's feelings about leaving home are only made more complicated when she connects with Addisyn's attractive older brother, Ryder. As summer draws to a close, the girls must face their paths forward-for the first time--on their own.
