My Dad and the Volcano

A story of a father and son and... a volcano. Gavin built a 6-foot volcano and he asked his Dad if he could store it in his shed for a short while until he figured out what to do with it, but that turned into five years and his Dad has threatened to destroy it over the years. Gavin aspires to bring him and his Dad together through the volcano, to help his father see it as he does. However, there's a challenge - his dad holds no interest in modern art and has declined any involvement in the documentary.
