The series starts with a flashback, way before the present day, where Thor ask for all the help of the gods in the Marvel Universe to fight off the world serpent, Jormungand. All the gods heed Thor's call except for one, Seth, who was promised by the world serpent that he will be given absolute power over the Egyptian gods and will rule over them when Jormungand defeats Thor. Angered by his betrayal, Khonshu fought Seth in a duel and the former won. As Thor and the other gods celebrated the defeat of the world serpent, Khonshu sealed Seth underneath his own temple so he could guard him personally, Seth swore revenge.

Back in the present, when Bushman's men was ransacking the temple of Khonshu in the 1st episode, they unknowingly opened the chamber that sealed away Seth. Seth's spirit was freed and bent on revenge on the one who sealed him in the first place, but he couldn't feel the presence of the Lunar god and thought that he has left the land. Seth then finds a person that he will become his "avatar of death", but he must find a more suitable host that has hands that are blood-drenched with all of his victims that he does not want to wash. He hears of a mercenary that was defeated by a "man in a cowl who returned back from the dead". Curious, Seth seek out this mercenary and found him in an old apartment. It was Bushman, drunk and still missing alot of teeth as a reminder of his confrontation with Moon Knight. Seth then begins to scare Bushman and while still very much drunk, shoots violently all around trying to kill whoever was talking to him. Seth then appears as an apparition before Bushman and told him that he will be his avatar of death, where he offered him superior strength and vengeance to the person that made him like this. Bushman agreed to this and Seth touched him and he received a death's hand mark in the face and felt all the power flowing within his body. Bushman later goes to a blacksmith and have him fashioned a pair of metal dentures. After the blacksmith made him the dentures, Bushman bit off his face and killed as a "thanks" for his work and then left to America to finish off Marc.

Back in New York, Moon Knight is having a conversation with Frenchie while kicking a local gang's ass at the same time. All of a sudden, Moon Knight begin to have a seizure and Khonshu spoke to him, to come back home and that he has urgent news for him. Frenchie saw Moon Knight collapsed and quickly came to the aid of the fallen superhero. When they got home, Marc took off his costume and still experiencing the effects of the seizure, goes to a room replicating the altar where the statue of Khonshu is resting. On his way, Marlene asked what was going on, but Marc was replied nothing. Entering the room, he locked the doors and Marc experience another seizure. Marc was howling in pain as Marlene and Frenchie tried to open the door with no avail. Inside the room, Marc had an out-of-body experience much like what he did in his first encounter with the lunar god. Khonshu informs Marc that a great evil is coming to get them, it was his Bushman and he is being accompanied by another god whom he had imprisoned long ago. Khonshu advise Marc that this will be the fight for his life and he should prepare for the inevitable.

The next day, Marc goes out in the street in his Jake Lockley personality to try and find where is. At the airport, Bushman had just arrived and with a twist of fate, Bushman hailed Jake's cab. The two rivals didn't recognize to each other, but their respective gods immediately confronted each other in the astral plane, taunting each other on whose avatar is the best. After that, each god telepathically told their avatar the identity of each other. With this knowledge, the two of them had a long stare down inside the cab. As their gods persuade them to attack each other, they don't comply to this and Bushman left the cab. Khonshu ask Jake why he didn't attack, and he replied that it wasn't time yet. Bushman stare at Jake's cab as it left with a very evil grin in his face. Later that night, Marc came back to his mansion. What he saw was everything was destroyed except for the temple room and Frenchie, beaten to a pulp. Frenchie told Marc that Bushman came and took Marlene hostage and that if he wanted to see her alive, he would meet him in a warehouse in the docks. Marc goes suits up and first proceeded to the temple room and asked the lunar god for the power to defeat Bushman and Seth, but he declined. Instead, Khonshu possessed Moon Knight and his costume change into that of being the fist of Khonshu he was granted more power originally given to him. Khonshu said that they will fight side by side to defeat the avatar of death. Lastly, Moon Knight wondered why the room was the only one that wasn't destroyed and Khonshu replied that the temple was sacred ground and it cannot be touch by evil forces. Moon Knight then set out to confront Bushman, Frenchie wanted to help but Moon Knight stopped him, telling him that he needs to sit this one out and that this is between Bushman and Moon Knight.

In the warehouse, Bushman is playing with Marlene, teasing her and contemplating on how he will kill both of them after it was over. Before he coudl do anything to Marlene, he was stopped by Seth and reminded of his mission to kill the Khonshu's avatar. Suddenly, Moon Knight busted open the door and called Bushman out. Bushman came and Moon Knight commented that he will pay for he had done to him. And in the voice of Khonshu, he called out Seth and said that there is no use hiding and that they will settle this through their avatar. Seth, not to be intimidated, possess Bushman to "level the playing field" and the fight between the avatars begin. The fighting was brutal, bloody and downright ugly. Bushman fought with guns, while Moon Knight fought with his customised weapons. Even though Bushman is an expert in guerilla warfare, Moon Knight can right to him because of his powers. But when Moon Knight was caught off guard, Bushman strikes and has almost bitten off Moon Knight's face. With a bit of a struggle, Moon Knight manage to break Bushman's steel teeth thanks to the boosted power given to him by Khonshu. Seeing his defeat is inevitable, Seth abandons Bushman saying that he was wrong to choose him. Moon Knight took pity at his defeated enemy and left with Marlene, but Bushman wanted nothing of it and tried to attack Moon Knight from behind but he this was coming and struck him again in the jaw and completely destroyed it.

At home, Marlene told Marc that she now understand him more and that she is now more supportive of him and his motives, but she worries about him that he is trying to get himself killed in the process. Nevertheless, she and Frenchie are very much proud of him. At the same time, the Committee has ask David to look on the profile of a certain Steven Grant..
