Producer Pam Voth and director Rob Whitehair's heartwarming documentary charts the travels of the Missoula Children's Theatre Little Red Truck, a touring theater group that moves from city to city to put on productions cast with local kids. For over 30 years, MCT has moved from one U.S. town to the next, recruiting children from the area to join them in taking on the feat of mounting a full-scale, one-hour musical in one week's time.
