OPEN NET is another inimitable account of an amateur"s foibles meeting the world of professional sport. George Plimpton takes to the ice a goalie for the Boston Bruins, after first signing a document holding the team harmless if he should meet with injury or death as their amateur goaltender. He survives a game against the Philadelphia Flyers relaticely unscathed - and brings back this memorable portrait of the rough-and-tumble world of professional hockey.
