They are placed again into Hammer's automobile which then is pressured off a cliff. Hammer wakes up in the sanatorium. Velda, his trusty secretary, informs him that Christina is lifeless. Pat Chambers, Mike's policeman buddy, tells him to live off the case, but Mike thinks it is probably a big tale--meaning massive money for him--because the FBI is interested. He, Velda, and Nick, his storage mechanic pal, start investigating in hopes of finding out why Christina turned into killed.
