What Might Have Been(2019)

Astrid is in her late forties and has her life firmly under control. She has fallen in love with Paul, and their first weekend trip together takes them to Budapest for a few romantic days, just the two of them. But in the Hungarian capital things happen differently than they'd planned: They run into Julius, Astrid's first great love, whom she'd met at an artists' party in East Germany in 1986.
