This document summarizes the key events in Franz Kafka's short story "The Metamorphosis". It discusses how the protagonist, Gregor, transforms into a giant beetle and becomes alienated from his body, mind, and social relationships. This creates a sense of isolation for Gregor from both society and his family. The alienation grows larger as Gregor's family becomes more frightened and distant towards him. In particular, his sister Grete eventually betrays Gregor in an attempt to gain approval from their parents. The transformation leaves Gregor as a lonely and isolated figure.
