The main character of the game is a five-year-old boy. His parents divorced, and now he lives in a house on a hill with his mother, who watches Christian television all day. One day, she hears a voice that tells her that her son is unclean and that she must sacrifice him. "Yes, Lord," the woman replied, took out a kitchen knife and went to kill her son. Isaac overheard all this, trembled with horror, but at the very last moment discovered that there was a trapdoor leading to the basement under the carpet in the room, and jumped there.
It is from this moment that his adventures begin...
The story of this character is a reference to the biblical parable about Abraham and his son Isaac.
