Including LEGO set spoilers and just about everything we know so far

The movie likely opens with Wanda and Vision staying together at this hotel in Edinburgh. After heading outside, they are attacked,

with the Mind Stone nearly successfully extracted from Vision,

leaving him injured.

But a timely rescue from Team Cap

allows them all to escape, and head back to the Avengers compound, with Vision still injured.

They meet up with Rhodey and Bruce and then head to Wakanda.

Shuri offers or agrees to help extract the Mind Stone (if the LEGO set is accurate) or help heal Vision.

Wanda and Vision stay with her as the rest battle Thanos’ army. It appears eventually things get dangerous enough that Wanda and Vision leave for the jungle, with Vision’s Stone still intact on his head, and Vision sitting on the ground, looking injured, and both know something is coming.

One last note, is that the Entertainment Weekly article mentions that Vision feels pain as the other Stones draw near–this could be inaccurate from them (because they do report some things wrong), but if so, it could mean that Vision was not damaged from the battle, but is reacting to the approaching Stones. Vision might be sensing them approaching, and that might be what Wanda is investigating here:
