Paranormal investigators Lacey Fitzpatrick and medium Sam Firecloud discover their reputation has spread around the world when they get a surprise call to investigate ghosts in an Irish castle. They’re even more surprised when they learn it’s the Castle Fitzpatrick, the ancestral home of the Fitzpatrick name, and Lacey’s hopeful she can uncover some of her own family’s history. But while they’re researching that and the ghosts that Sam’s walk has revealed, they get unexpected resistance from the castle owners. If Sam is wrong about the impressions he’s received from the spirits, the releasement won’t work, and the ghosts will be doomed to walk the castle forever.
