According to Variety: “[The] plot is said to involve David and Hamm as characters who each invest in an electric-car company with different goals in mind. When the car becomes a success, David’s character gets his investment back, while Hamm’s businessman becomes extremely rich, causing tension between the duo. Keaton is being recruited to play a crazy businessman named Stumpo, who is David’s friend.”
