Fortune is thrilled when Ben Harrison, her former CIA partner, and his fiancée, Cassidy, decide to leave DC and move to the Louisiana bayous. They've already secured jobs and are only lacking a place to live, so everyone is excited when they quickly find a home. There's only one problem-the house has a reputation. It's haunted.

Fortune doesn't believe in ghosts, but when Cassidy starts seeing a woman in white inside her house and can't determine how she's entering or exiting, Fortune knows she's got to figure out what's going on before things get worse. As Swamp Team 3 takes on the "spirited" case, they dive into a decades-old mystery of love, money, voodoo curses, and a missing woman. But can they get answers before Ben and Cassidy give up the ghost and go back to DC?
