Lanier description:

Jeff Stevenson, his wife and daughter head off to a fun weekend getaway at Lake Lanier to celebrate his daughters birthday. The vacation turns into a work-cation for Jeff to solve a drowning case when he decides to go undercover to work on a drowning case to help a local detective named Daniel Wilson. As they work together, Jeff denies Daniel's theories that Lake Lanier is haunted, not to mention the history of the fallen city under the lake, Oscarville. A once thriving black community that was destroyed due to allegations of the rape and murder of Mae Crowe in 1912. Jeff's denial leads him to become increasingly concerned through a series of events. His worst fears soon become a reality when three masked strangers force themselves inside the home, forcing the himself and his family into a fight for survival.
