The band of misfits are settling into life on Knowhere, but it isn`t 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.
