After losing his position as a minor-league pitcher, Montgomery Brewster learns his great-uncle has left him 300 million dollars. To inherit it, Brewster must spend 30 million in 30 days under a complicated set of rules that forbid him from donating too much to charity or retaining any new assets when the period is up. Unable to share details about the will's odd conditions with anyone, Brewster sets out to spend his money under the stern eye of paralegal Angela Drake.
