When Timon falls into debt and seeks help, those he aided abandon him completely. Betrayed and embittered, he retreats to a wilderness cave, renouncing all humanity. There he discovers gold, attracting visitors with various motives while he descends deeper into misanthropy and rage against mankind. (This is an automatically generated summary.)
