Sculptor Tom Luckey was gearing up for his biggest project yet - a towering climbing structure for Boston's Children's Museum - when he fell out a window and was paralyzed from the neck down. With help from wife Ettie, Luckey drafted his grown son, Spencer, to finish the job. A heartwarmer about family bonding in the face of adversity? Not really. Laura Longsworth's documentary is about two type-A personalities battling bitterly across a generational divide, wrestling questions of authorship, art, and hardware to the ground.
