A road map would have helped with the plot. The sole redeeming feature of the entire film is Eric Burdon. I believe he has little or no professional training so he simply plays himself. A better plot and director may have produced something of a classic but sadly, that was not the case.
It was if there was more going on that advertised so don't leave the room then "comeback" because you will think someone changed the channel. Worth a watch for Eric and the camera work which also has strength.
The music is a great example of Eric's work while he has been in exile after being blacklisted by the power brokers of the American music industry.
