When their son Waldo is just six months old, Brian and Danielle Dwyer notice that he's experiencing difficulties with his vision. Receiving the devastating diagnosis of eye cancer, the parents follow doctors' orders and begin chemotherapy on their infant. But when the chemo causes Waldo to become violently ill, they begin a desperate search for alternative therapies, and what they come across is an all-natural, chemical-free option: weed. Alienating their friends, colleagues, and family-and without telling their pediatrician-Brian and Danielle make the controversial decision to treat Waldo with CBD oil. The triumphant results are captured in the film which includes joyous footage of the family as they uplift their lives from Philadelphia and build a new home on a cannabis farm. This documentary is a love letter from father to son.
