What Charlie doesn't know is that this is Itchy's twentieth mission, and if successful, he will be reallowed entry to Heaven. With the separation between him and his best friend at stake, Charlie struggles with moral dilemma: to deliberately tank the mission or help out and let Itchy go back to Heaven.
