Kryger bleibt Krüger

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.

Berlin pensioner Paul Krüger looks forward to lead his fatherless-raised pregnant granddaughter Annie to the altar, but Turkish groom Denis's sugar uncle insists due to Anatolian family honor tradition on the presence of her biological father Harald, whom her mother Susanne never even told about their child having broken up. Knowing only Harald moved to Greece, Krüger takes his pétanque (bowling) pub buddies Ecki and Bernd along to Hellas, a country they know nor trust. Equipped only with an old photograph, they find themselves on the wrong island, upsetting the wrong shopkeeper's family. Having crossed to the right one, they wander into a tempting German free sex commune, before even learning Harald is now an orthodox monk in a monastery, which observes lent silence, albeit without fasting. The clergyman won't consider returning until Paul calls in unenthusiastic help, and even then the monk isn't on their plane back.

Paul Krüger and his drinking mates can't accept their beer pub "Flachbau", reaching its 25th jubilee, is about to be closed because the publican Karin fell in love Internet-dating mundane gastronome "Hansi" Falkenheyn Waldstätten and wants to start a new life in his native Austria. Krüger and his buddy Bernd, who has a never-declared crush on her himself, leave Ecki 'guard the fort'in Berlin and travel to Salzburg to stop her wedding preparations. Krüger and Bernd's theory the groom may merely be after the Flachbau sale proceeds is unexpectedly confirmed by their local gentleman inn keeper Poldi, a charming ladies men who volunteers to sabotage scam artist Hansi, to whom he lost a meanwhile ruined lover, leaving only Karin to be forced to learn the truth about her groom before he gets her to the alter, a matter of hours.
