In the shadows of New York City lies the abandoned, forbidden North Brother Island, where the remains of a shuttered hospital hide the haunting memories of quarantines and human experiments.

When Finn, a young urban explorer, arrives on the island and glimpses the enigmatic woman through the foliage, intrigue turns to obsession as he seeks to uncover her past – and his own family’s dark secrets.
