In this classic tale of good vs. evil, Finn arrives at HALO school, joining six other teens as part of a special group within the angel world. When an unexpected turn of events puts the fate of the group in jeopardy, they must save themselves, or all of humanity will perish. The fledgling angels, not yet prepared, are forced to travel into dangerous demon territory, where their skills and talents will be sorely tested. Will they survive?
