The next morning, Sammy Jo comes to Jeff's apartment to accept his proposal, not knowing Fallon is hiding in his bedroom.

Fallon becomes romantically involved with John Zorelli, the police officer investigating the case — much to Blake and Jeff's dismay.

The dead body turns out to be Roger Grimes, the man with whom Alexis was sleeping when she and Blake divorced.

The situation is complicated by the fact that the mine is full of stolen Nazi treasure, also hidden by Tom.
