Anthony is a young man who was born and raised in Tokyo and is now raising a family there. What should be a happy time in Anthony's life is not: his wife is crippled by anxiety and unable to leave the house. She also has recurring nightmares about a horrible fate awaiting the pair's young son, Tom.
Those nightmares turn out to be prophetic when Tom is cruelly run down in the street. Losing their boy pushes Yuriko over the edge and triggers violent emotions in Anthony, whose body begins to transform. Anthony flies into a terrible rage, and soon discovers that the power of his emotion transforms him into a strange, metallic monster.
