"Guardians of the Galaxy" introduced many otherworldly characters and settings to the MCU in a risky shift of tone for the movies. After his mother's death in 1988, Peter Quill gets abducted by Ravagers and raised in space. Now he's stolen a curious orb that begins to get him in trouble with not only Yondu, but with the maniacal Kree extremist Ronan who also wants what's inside the orb. Thanos's deadly warrior daughter Gamora tries to get the orb, while Rocket Raccoon and the tree-like Groot try to capture Quill. That gets them all thrown in prison where they meet the powerful Drax the Destroyer. After the unlikely team escapes, they make their way to Knowhere to sell the orb. But they learn that there is a powerful Infinity stone inside which Thanos also wants it. Ronan shows up to cause trouble and gets away with the stone. Now the Guardians have to help save the planet Xandar before Ronan destroys it all. This bunch of losers may have just what they need to save the day. Jay and Josh strap on their Walkman and hit play on the most epic space mixtape ever made on a hiatus special of Agents of S.H.I.E.L.D.: Case Files.
