After a tragic event that could have been avoided, Lucy lives with a regret that clouds her days making life unbearable for herself and family. Hoping to find a renewed sense of meaning, she goes on a mushroom foray in the wilderness. But rather than finding a reason to live, she plays Russian roulette with mushrooms that resemble destroying angels (a type of deadly Amanita). There she befriends Paul, a graduate mycology student with optimistic dreams on the scientific applications of fungi to heal our planet. He unwittingly finds himself in the middle of her painful journey and in a race against time upon putting the pieces together. Meanwhile, floating between life and death Lucy still has choices.
