Over the last 25 years, supernatural beings from around the world have been abducted and subjected to DNA experiments at The Facility, aiming to create a super-warrior. Their sole success, Pandora, escaped a decade ago with a group of residents and now seeks vengeance.
 
Raven has brought Elijah and his Elite Warriors to Sanctuary, her people's refuge. She assures Elijah that he will find all the answers he seeks about The Facility, its inhabitants, and his own people who were abducted 25 years ago. However, the residents are reluctant to share information, avoiding Elijah, and he is determined to uncover the reasons behind their evasiveness.
 
Raven, Caleb, Elijah, and his Elite Warriors from the Underworld form a plan to bring down The Maître, the mastermind behind The Facility. However, Raven's persistent secrecy deepens Elijah's mistrust of her.
 
Roman experiences a sense of déjà vu with Raven, leaving him uneasy. The secrets she withholds intensify his determination to break through the emotional barrier she has constructed. Raven recognizes Roman's unwavering commitment, but she fears that once he uncovers all her secrets, he might choose to leave. The situation is further complicated by Raven's daughter, Salem, who has developed a strong attachment to Roman.
 
Salem unintentionally reveals a secret about Raven, triggering Elijah to launch an attack on her. Their intense fight requires Roman and Caleb to intervene, preventing Raven from killing Elijah. In the aftermath, Elijah refuses to help Raven further until he meets the elusive Pandora.
 
If Raven and Elijah fail to establish trust and find common ground, their mission is at risk of failure, jeopardizing the freedom of both Raven's and Elijah’s people. Years of fighting to protect her people will have been for nothing.
