Lee Hayden (Sam Elliott) is an aging Western icon with a golden voice, but his best performances are decades behind him. He spends his days reliving old glories and smoking too much weed with his former-co-star-turned-dealer, Jeremy (Nick Offerman), until a surprise cancer diagnosis brings his priorities into sharp focus.

He soon strikes up an exciting, contentious relationship with stand-up comic Charlotte (Laura Prepon), and he attempts to reconnect with his estranged daughter, Lucy (Krysten Ritter), all while searching for one final role to cement his legacy.
