Tom Holland stars as a young (something that Twitter pulled up the series for earlier after Tom's casting) Peter Parker trying to fit into his high school life while simultaneously shouldering responsibilities of a crime fighter and prove that he's not an 'ordinary kid.' The film probably doesn't delve into how Peter Parker became Spider-Man (at least for now), something which previous films with Toby Maguire and Andrew Garfield highlighted.
The events of Spider-Man: Homecoming starts after Captain America: Civil War, where Spider-Man fought on Team Iron Man against Team Captain America. Tony Stark, being his usual funny and sarcastic self, is there to guide Peter and has designed some useful additions for his suit - like web-wings. Totally cool.
In the last scene of the trailer, Spider-Man and Iron Man flying in-sync determined to reach their destination.
