Billy Arnet's girlfriend falls through a skylight, to her death. Peter Gunn is hired prove it was not an accident but murder.

An escapee from a mental hospital gives the Mayor an ultimatum, either commit suicide or a bomb will be detonated at the Civic Centre.

Cesar Carlyle, a very rich man, hires Gunn to find certain documents which, if made public, could ruin him. Seems the papers were stolen and the theif wants a good deal of money for their return.
