Earl Stone, in his 80s, is an award-winning horticulturist and Korean War veteran in Peoria, Illinois. He is facing financial ruin and is estranged from his ex-wife, Mary, and daughter, Iris, for always putting work before family. Facing little suspicion due to his age, race, spotless criminal history and strict adherence to driving laws, Earl is soon trusted with huge amounts of drugs and paid large amounts of cash. With the money he obtains from drug-running, he buys a new truck, settles his financial problems, pays for renovations of the local VFW Post and his granddaughter's wedding and education. Tensions within the cartel erupt when a power-hungry lieutenant assassinates the boss, and subsequently demands Earl be kept under tighter control. In the middle of a large cocaine shipment, Earl learns that Mary is gravely ill. After Ginny talks some sense into him, he postpones the drug delivery to make peace with Mary before her death, which provokes the cartel's ire. He resumes the delivery as the DEA and the cartel close in on him. Earl is beaten and threatened by the cartel's enforcers, but they relent after learning of his ex-wife's passing. As he makes his way towards the drop point, he is arrested by the DEA agents. When Earl pleads guilty to all charges and is sent to prison, his family show him their support. In prison, he returns to his horticulture.
