What begins as a fun night of sharing ghost stories in a local graveyard soon turns sour when twelve-year-old Delta, her younger brother, Jax, and their friends are falsely accused of vandalizing a historic site on Hilton Head Island.

Can Delta and Jax actually change history, and, perhaps more important, should they?
