Kolchak writes an obituary for a deceased scientist, but soon becomes involved in further investigation when no one can give him a straight answer on how the scientist died. Meanwhile, a mysterious figure goes on a rampage throughout Chicago, stealing morticians' wax and Halloween masks. Kolchak eventually finds out that the scientist was working on Project R.I.N.G.: the development of an artificially intelligent robot. R.I.N.G. killed his creator rather than be shut down, and now the government is hunting it. Kolchak must find where the robot is hiding and reveal the story before the government catch up to R.I.N.G.

Un robot tue son créateur et s'évade pour vivre comme un être humain mais devra tuer encore pour survivre car Mr R.I.N.G. a peur de mourir. Kolchak part à sa recherche pour lui venir en aide.
