Kevin Finn is struggling. Directionless and cluelessly self-serving, he seems to be drifting ever closer to total despair. With his life spiraling further and further out of control, he heads home to seek refuge with his widowed twin sister, Amy, and her young daughter. On his first night there, life takes an unexpected turn when he receives an unlikely celestial being named Yvette, who has a mission for him: to save the world. It's going to take a lot of trial and error, but maybe a bigger purpose is exactly what he's needed all along.
