This 1978 commercial is for the company called St. Regis, which is a a maker of plastics. 

The clip begins with a bull fight underway. There are profile shots of both bull and matador. The narrator tells viewers that between the bull and he matador, lies two sheets of plastic. 

Zoom in to show the bull making several attempts to puncture and break through the plastic. The shot widens showing reactions from the crowd, we hear cheering. 

Zoom out to a forest with head-high stacks of paper products, our narrator is walking besides the stacks, describing St. Regis business ethics. An aerial view shows that these stacks make up letters spelling "St. Regis."
