Guardians Of the Galaxy – Movie (PG-13) Sci-fi, Adventure, Action, Fantasy, Comedy After acquiring Knowhere from the Collector, we find the Guardians working to repair the extreme damage done by Thanos-determined to make Knowhere a haven, not only for themselves, but for all refugees displaced by the harsh universe. But it is not long before their lives are upended by the echoes of Rocket's turbulent past. Peter Quill, still reeling from the loss of Gamora, must rally his team around him on a dangerous mission to save Rocket's life-a mission that, if not completed successfully, could quite possibly lead to the end of the Guardians as we know them.
