This is a very good story, with good acting and a good finish. The story has been well told -- I don't know how many of my favourite characters from '60s TV had old friends return -- and turn out to be bad.
This is again the case. Richard Anderson (popular guest star in the '60s), appears as an old friend who had previously saved Lucas years ago.
Lucas is afraid he's gone bad, and wants him to understand that if he hurts North Fork (his bank), that it hurts him.
He tells Lucas he's riding off to Denver -- and is gone in the morning. Mark, however, saw him ride off -- and tells his dad it was towards town.
Lucas immediately rides into town. A good story, who's end I won't reveal. Worth watching.
