Lanky, weak and nerdy. That is how Sungjae like. He is frequently looked down, bullied and humiliated. However, he doesn't mind at all and he accepts all kind of harsh treatment from the others. Well, sometimes he does complain that his life ... But still, he never stands up for himself.

A sweltering afternoon during the school trip in Jeju, Sungjae is arranged to group with five others people from his class to complete a game. Expectedly, people don't even acknowledge his existence. As they are venturing the woods, Sungjae is left behind. He is lost in the woods, alone. 

Howling and growling of the creatures make his hairs stand up to the end. Things happen vaguely and Sungjae blacks out. When he is awaken, he finds himself in a cave, surrounded by a pack of wolf.

What is going to happened next?

Is Sungjae going to be eaten alive? Or, his life will change for the better or worse?
