The Aliens
外星人来了。事实上，他们已经在地球上待了40年。尽管他们长相像人类，说话像人类，行为也像人类，但他们不准和人类共同生活。政府将外星人限制在一块叫 「特洛伊」的聚居区，那里四周高墙环绕，危险的、非法的、禁忌的事情层出不穷，而且还带有强烈的神秘感。
Lewis is a border guard at a checkpoint that patrols a wall, but after a chance encounter with mysterious alien Lilyhot his life is thrown into turmoil when he discovers that he's actually half alien.
After Lilyhot reveals to Lewis that his real alien father Antoine is in prison, he agrees to help break him out. Truss starts to believe that Lewis is involved in some shady dealings.
Lilyhot attempts to persuade Antoine to take part in a gang war with Fabien, assuring him that he can retake control of Troy.
Truss follows Lewis to Troy, where he discovers that Lewis is half alien, but the Alien League spots Truss, which puts him in grave danger.
Dominic is forced to become a hitman, while Lewis is blaming himself for what happened to Truss. In Troy the gang war between Antoine and Fabien is escalating.
Troy is put into lockdown, and with the help of Lilyhot, Lewis realises he has to bring the conflict to an end, but to do so a sacrifice must be made.
