According to CanWeGetSomeToast, the core contradiction in "Captain America 4" will revolve around Sam Wilson's identity as Captain America.
It is reported that in "Team America 4", Sam's identity as Team America is not officially recognized, although at the end of "Falcon Winter", Sam has put on the uniform of Team America and taken back the shield, but for the US government is not officially recognized this. (Original by Captain Super Hero)
As a price for awarding Sam the title of Team America, Ross intervened with Sam, who wanted Sam to serve the U.S. government as Team America, just like the previous "Team American" John Walker.
But Sam resists this, and he wants to inherit Rogers' will and protect peace as a free hero. The conflict between these two ways of thinking made a conflict between Sam and Ross.
According to reports, the story of "Captain America 4" is very similar to "Captain America 1", after Steve became Captain America, he did not go to the front line at the first time, but became a tool for government propaganda, touring the world in exchange for sponsorship.
In the movie, Ross is actually very close to Sam because he does not believe in superhumans, and Sam is an ordinary Captain America, he is very happy about this, but he is very annoyed by Sam's stubbornness. (Original by Captain Super Hero)
It has been previously reported that "Captain America 4" will be a "Civil War 2.0", and there will be an infighting between Captain Falcon and President Ross.
