So while reading an article about the movie I decided to post a comment about what I believed the plot would be, then I realized how long it would be and decided no one would read a comment that long. So I decided to write a article about my ideas instead. Beware there is a 0.5% chance threat my ideas will make it into the movie so BEWARE SORT-OF POSSIBLE SPOILERS.
Berfore I start I want to that I believe the movie will have two main plots (cutting continuously between the two) that merge in the end of the second act.
The first plot will be the story of the earth heroes and the turmoil after Civil War
The Second will be the story of Thanos grabbing the Infinty Stone which involves The Guardians and Thor
i would also like to let you know this isn't a detailed scene by scene of the movie but a more general plot
So with that out of the way this is the plot of the movie...
We start Captain Americas secret Avengers consisting of Cap, Falcon,Wanda,Hawkeye and Black Panther(who is now funding the team) running around the world and stopping bad guys covertly. Although Wanda struggles to use her powers after the events of Civil War. Despite doing good work the team is struggling with be secret Clint wants to see his family, Scott his daughter, and Wanda the vision. Cap has to constantly remind them why do what they do. While hiding in Wakanda while Cap checks on Bucky's Progress they receive an alert threat Baron Zemo's Masters of Evil including Zemo now in his classic suit,Abomination, Vulture,Erik Killmonger,Klaw, and Justin Hammer (still working out this team due to the villains from the remaining solo movies)have recently broke out of prison. So the team tracks them down and heads to confront them but as they arrive and engage they are overpowered. That is until Tony Starks Avengers Team of Iron Man,The Vision, Spider-Man, and War machine who now relies on his suit to battle.
After the Two teams reluctantly work together Tony and Steve argue again, leading to Cap's escaping by releasing some villains. As they Return to Wakanda Scott decides he must leave to see his daughter before they get arrested again(leading into Ant-Man and The Wasp). While on Tony's side he decides he imprison Cap's team once and For all.
Meanqhile on the other side of the Universe we find Thanos who fenters to collectors home and demolishes everything in order to find the Aether. After killing the collector and many others he arrives to his ship claiming he is halfway done with his mission to collect the Infinty stone(2 of which he found in post-credits scenes in other movies). He describes his love and goals to mistress death who ignores him. In his next scene we find him arriving on Xandar where he easily destroys the Nova Core and grabs the purple stone(sorry I forgot the name and am too lazy to find it out) he then leaves stating he is heading to Asgard. But before we leave the planet the Guardians of the Galaxy arrivé on the destroyed Cander, where Gamora realizes this is the work of Thanos and finds out a earthling hold one of the two remaining Infinty Stones. In his Next Scene we see Thanos arrivé on Asgard, he easily goes through the asgardians and has a slite trouble with Hulk and Thor. After defeating them he heads to Odins Vault to get the Tessarect, but Odin is there and they have an epic battle with Thanos eventually winning. We watch Thanos still after he walks through the valley of dead asgardians not realizing some are still alive.
now we get to the part where they merge, Tony is finishing his plans to capture Cap when suddenly an alien vehicle approaches the earths atmosphere. As he suits up and calls the avengers to intercept it the ship crash lands in New York with the Guardians Climbing out. After a quick battle where Tony states the last aliens weren't so nice, and some banter between the two teams The avengers listen to the Guardians explain the situation. Tony then conflicted decides to use the phone Cap gave him to call Steve to arrange a meeting a s something horrible is happening. The two teams meet and after some brief hostility they all join together and devise a plan to stop Thanos when he arrives.
The Avengers and the Guardians then enter a spacecraft created by Tony and head to space to find Thanos, they find him on a planet outside their solar system. As they arrive Thanos creates a makeshift army which the teams struggle with but eventually defeat. Tony exclaims that was easier than he expected. Thanos than laughs and thanks them for bringing him what he wanted the stone he then rips the stone out of the visions head and kills him. Scarlet witch who had reconnected and expressed her love to vision before they left earth is horrified. Thanos then sees his Daughter Gamora and captures her, the teams decides they must escape and Thanos lets them as they are nothing to him a GOD. The movie ends with Thanos snipping his find and destroy hundreds of planets.
In a credits scene Afam Warlock Hatches out of his Cacoon
while in another Doctor Strange is meditating when he realizes what has just happened.
