Rude Awakening

After the strange, unexpected, and mysterious death of 15-year old Bebout Bachouri, an unsettling sense of paranoia and untrust falls upon the town. Conspiracies and rumors spread like wildfire but no can solve the case as to how Bebout dies... except for himself. With no one else willing to solve his case, Bebout risks his soul by leaving heaven and appearing on Earth in ghost form. With only a year to solve the case before he's banished to hell, Bebout will have to combine his newly found ghost abilities with the help of the cancer-stricken cheerleader and the only nerd in town to find the identity of the Siren Serial Killer.

This is the point where I would say he's doomed, but he's already dead.
