Two former high school lab partners stumble on a mushroom that can heal almost anything, apart from the corporate interests of the DEA, big pharma, and international businessmen.
Marshall Cuso shows up in NYC with a mushroom, that can cure any disease or injury; his old classmate, Frances, meets him by chance, but keeps secret that she works for Reutical, a pharmaceutical company.
Marshall buys a plot of land near a chemical waste site with a plan to grow more mushrooms; Frances rushes home from Europe after a huge development; Copano and Harrington investigate a connection between Marshall and Frances.
Marshall arrives in jail and learns that some important people refuse to let him out, while danger lurks around every corner; Frances makes a fateful decision; Copano and Harrington pick up the pieces.
Another inmate rescues Marshall, but now Marshall owes him a favor; desperate to get out of prison, he works on a risky plan when he runs into a surprising ally; Frances grapples with a life-changing event.
