Katie, Craig, and Mikey are the final three members of a cult that has prepared for years to achieve transcendence by stepping through a luminous portal in the woods. After completing their final duties, the trio enter the portal... only to find themselves back at the start of the previous day. In an attempt to transcend, the trio must figure out why they are unable to get through the portal as their fellow cult members did. Will adhering closely to the cult's teachings help them finally achieve perfection, or will they need to learn more about themselves - and each other?
