Phoenix was born into a circus family. His father Orgo was a knife thrower and his mother Concha was an acrobat. One day a woman saw Orgo dating a young tattooed woman. In a fit of jealousy, Concha threw acid in her husband's face. In retaliation, he cut off both of his wife's hands and then slit his own throat. All would be nothing, but it happened in front of little Phoenix. Naturally, the boy ended up in a mental institution.
After many years, he is released and settles down with his armless mother. Phoenix stays home all day, helps his mother cook meals, and tries to invent an invisibility formula. As Phoenix begins to visit his childhood memories, a string of brutal murders begins in the city.
