1988: Quill watches his mom die in a hospital. She mentions that his father is an "angel" and that he's coming to retrieve him soon. Quill gets abducted by aliens.
Now: Quill, part of a gang of thieves led by Yondu, finds a gem on a desolate planet where Ronan has also sent people to retrieve it. Quill escapes them and tries to pawn it on Xandar, but is refused when the buyer finds out Ronan is also looking for it. Thanos sends Gamora after Quill to retrieve it instead. Rocket and Groot are also on Xandar looking for bounties to collect when they see that Quill is wanted. All three chase Quill around Xandar before getting arrested by the Novas.
Ronan's introduction: he has a deep seeded hatred of the Xandarians and wants to undermine a peace treaty between them and the Kree. Thanos instructs him to use every means to acquire the gem, and in return he will destroy Xandar for him.
Quill and the gang meet up with Drax in the Kiln who intends to kill Gamora because she's an ally of Ronan, who had previously killed Drax's family. Gamora explains that she actually intended to betray Ronan and Thanos and sell the gem to Collector to buy her way away from Thanos. Rocket hatches a plan for them all to escape and they agree to work together to split the gem sale 4 ways (Drax doesn't want the money, he just wants Ronan dead, so he agrees to help for that). They escape the Kiln.
They go to Knowhere to meet Collector, who keeps them waiting. Drax and Rocket get drunk at a bar and do some gambling while Quill and Gamor exchange backstories - she educates Quill on just how horrible Ronan and Thanos really are and what they intend to use the gem for. Drax, Rocket and Groot get into a drunken brawl before leaving Drax in the street while they meet Collector with Gamora and Quill. Collector educates them on the nature and origin of the gem and it's counterparts. Collectors slave assistant tries to use the gem to free herself, but she can't wield it. It eats her alive, causing a violent explosion that destroys Collector's entire trophy room (Cosmo, in one of the display cases, get's set free and runs away!)
They attempt to flee with the gem, but return to street to discover that Drax in a drunken stupor alerted Ronan to their presence on Knowhere so that he could confront him. Ronan beats the **** out of him while the rest get chased by his soldiers. They lose the gem. They make a pact with Quills gang, the Ravagers, to try to retrieve it so they can get it out of Ronan's hands.
Ronan defies Thanos' authority and merges the gem with his hammer, making him even more OP. He threatens to kill Thanos if he tries to come after him. Nebula changes allegiances, saying that if Ronan can kill Thanos, he has her undying loyalty.
NOBODY LIKES THANOS.
The Guardians hatch a plan to return to Xandar and convince the Novas to help them make a stand against Ronan - suicide mission. Ronan attacks Xandar, the Novas make their stand with Rocket assisting, the rest of the Guardians infiltrate Ronan's ship to do battle and take the gem from him. Ronan wipes out thousands of Novas in one shot before the guardians take down his ship. Groot encases the wounded group in a cocoon, protecting them from the crash - Groot dies. After the crash they destroy Ronan's hammer, loosening the gem. Quill grabs it but it almost consumes him. Gamora and the gang grab on to him and their collective strength enables them to use the gem to destroy Ronan.
Xandar is saved. We learned that the Ravagers were sent to earth to bring Quill to his father, but Yondu opted to keep Quill for himself. We learn that Quill is part alien and that his alien physiology is what kept him alive while holding the gem - his father was someone really powerful, apparently. Rocket has a sprig of Groot in a pot with dirt, slowly growing back to normal. Drax pledges to kill Thanos, the real villain. They all fly off together. Baby Groot does a happy dance
