Tim Matheson plays a down-on-his-luck aspiring professional bowler. He has an elderly mentor who teaches him to believe in himself. He has a girlfriend who boosts him when he's low. He's got a whole bunch of down-to-earth buddies who support his quest. He triumphs over the mean-spirited bureaucrats who seek to deny him his PBA certification. He enters a national tournament as a last-minute add-on. He becomes a dark horse, striking and sparing his way into the finals, and finally taking the championship from one of his childhood heroes. Just like a thousand other sports-related movies, in fact. Rent Caddyshack or Kingpin instead.
