Berlin widower Paul Krüger, a retired ex-GDR stone mason (66), hates foreigner immigrants, especially Muslims. When his beloved, doting granddaughter Annie plans to marry Deniz, an ambitious student and waiter in Ankara who needs a visa for Germany, backward Paul and his buddy, publican Karin, go on Turkish 'holiday' so he can talk her out of it. But Deniz proves her only choice and probably a right one, even if countrymen and family win Paul's heart, as well as a resourceful preteen-thief, who proves an orphaned Syrian refugee. Paul even promises to plead with his counterpart, Deniz's family patriarch, who opposes him marrying a Christian infidel at pain of expulsion from the close clan.
