Robert Blake obviously created this story with "China Town" as its inspiration. His character, Joe Dancer, is entangled with a rich and powerful family with deep roots in LA. He is enticed and misled by a beautiful heiress. Other members of the family try to hire him away. There are some embarrassing secrets that are at the bottom of the plot as well as some political intrigue. Does this sound familiar?
The plot is helped along with some incredible "jump cuts" and implausible action scenes. Blake jumps off a water tower onto a moving train while carrying the body of a full grown adult! When he lands, no attempt is made to disguise the fact that the "body" is actually a poorly constructed dummy. Later, Blake handily disposes of a thug played by the towering Bubba Smith in a train yard fight. How the diminutive Joe Dancer achieves this feat is neatly obscured in darkness.
Unlike Jake Giddes, Jack Nicholson's flawed character in "China Town," Joe Dancer comes across as almost superhuman. I personally believe that this film reveals its star and creator, Robert Blake, to be an egomaniac of unusual proportions, even for Hollywood.
This is one of those films that is so bad, it is fun to watch. It is a testament to how a famous actor with a bad idea and a lot of influence can spin a flimsy plot into a Hollywood production.
