One girl's daring adventure turns into a long frightful night lost on the water.

Against her wishes, Dannie has to leave the California beach behind to spend the summer with her grandma in rural Tennessee. Things look up when a group of local boys invite her on an overnight kayaking trip. When her grandma refuses to let her go, Dannie finds an old rowboat hidden behind the shed and sneaks off to catch up to her new friends. It seems like a simple solution... until everything goes wrong.

Dannie soon discovers this lake is more than just vast. It's full of danger, family secrets, and ghosts.
