The sport of golf began in Scotland in the 15th century and arrived in the U.S. in the late 1800's. Its popularity grew, and in the 1960's charismatic professional golfers such as Jack Nicklaus and Arnold Palmer expanded its audience. Today, Tiger Woods and other players are full-blown celebrities. But what about the mysterious people carrying their bags around the golf course? In 'Loopers: The Caddie's Long Walk', director Jason Baffa shifts the spotlight to these individuals. At one time, the prevailing expectation for caddies was this: show up, keep up, and shut up. However, this inspiring documentary paints a different picture of these essential, unsung heroes, who often act as advisors, counselors, and confidants.
