TV-PG-V. Kramer and his old river-running buddies, Skinner, Mikey and Stan, are revisiting for the first time one of the most notorious rivers they ever ran when they were young river guides. This is more than just a reunion outing, however, as the four of them soon recognize that they all are "here for a reason." If they can learn to put the past behind them and pull together at a new level, they will rediscover a friendship strong enough to heal old wounds and give them renewed hope.
