They just posted a trailer:
Translated by CBR:
Set immediately following the brutal battle at Jaburo, the film sees the crew of the White Base traveling to a supposedly deserted island in order to track down a group of Zeon stragglers. While scouting the island in his Gundam, Amuro is separated from his mobile suit and comes across a group of war orphans and a former soldier, Cucuruz Doan, who has vowed to protect them. The peace on the island is shattered when White Base engages in battle with the Southern Cross Squadron, a team of elite Zeon pilots, and Doan is forced to confront his past.
