After being killed, Hub Halloran wakes up with claw marks burned on his arm and discovers he has supernatural abilities, including the ability to see demons that others cannot. He also finds he can see his own open neck wound in a mirror and has enhanced strength, as shown when he punches through a motel wall and overpowers a man sent to kill him.

The 'Pot O'Gold' corporation is a supernatural entity run by the Devil that recruits humans to sell their souls in exchange for personal gains, such as curing illnesses. In episode 1, Midge encounters a mystical 'Pot O'Gold' advertisement and is approached by representatives offering a contract to save her son’s life by selling her soul. This corporation is central to the story's supernatural and demonic elements.

Midge is a mother struggling to pay for her son Benji's cancer treatments. She is drawn into the supernatural world when she responds to a 'Pot O'Gold' advertisement and is offered a soul-selling contract by two representatives. Unlike Hub, she cannot see demons directly but can perceive supernatural elements through reflections in mirrors, linking her personal desperation to the larger demonic plot.

In episode 1, two Slypharis demons possess a newlywed couple and a fisherman during a violent scuffle at a local lake. These demons are part of a series of supernatural breakouts and sacrifices that Hub maps out, revealing they form a Satanic pentagram pattern. The demons are antagonistic forces that Hub attempts to track and confront but is unable to prevent harm before his vehicle is hit by a car.

Hub researches demonology and begins mapping the locations of recent demon breakouts and sacrifices. He discovers that these events are forming a Satanic pentagram shape, which suggests a larger, coordinated supernatural plan. This investigative approach drives his efforts to understand and combat the demonic forces at work.
