House of Taboo: Dark Oath

Crime lord Damien murders Adrian's family, adopts the surviving boy, and subjects him to years of control. Seven years later, Damien's daughter Evelyn reveals that she and Adrian are not blood siblings, and their suppressed bond crosses a forbidden line. Evelyn works with investigator Marcus to assemble evidence of the massacre and captivity. When Damien discovers the betrayal, he imprisons Adrian in the cellar, but Marcus delivers the case to the FBI.
