After being marked by The Hollow’s dark magic, Klaus and Marcel experience the symptoms of a malevolent haunting. Meanwhile, Hayley and Elijah head out to speak with Mary.
While Klaus remains behind with Hope, Elijah and a reluctant Vincent join the hunt, which puts them on a dangerous collision course with an unlikely new threat.
After five long years apart, Klaus attempts to reconnect with his daughter, Hope. Elijah mediates a conflict between Hayley and Freya to determine the best way to protect the family.
After being cured and woken, the Mikaelson siblings join Hayley in an effort to rescue Klaus from captivity, even if they must face Marcel in the process.
5 years after Marcel locked Klaus in “The Garden”, They all need to band together to fight a monster that could end their eternal lives as they know it.
