One day, for no apparent reason, you don't wake up. Your family assumes that you're in some kind of coma, but all the tests that the doctors do don't come up with any explanation.
But the thing is, you're not still asleep. Not really. Somehow, it's like your spirit has left your body, and you can see yourself sleeping in your hospital bed. You can see your family and all the doctors around you. But no matter how much you scream, cry, and try to knock things over, none of them notice you. You try even harder to wake yourself up, but it's no use.
So, what happens when you begin to wander away from your body, searching for answers? And, more importantly, what happens when you find out you're not completely alone after all?
