East German refugee Karin finds herself back at home in Dresden when the flight on which she is stewardess, between Berlin and the West, is forced down. She is then used by the State police to find her wanted brother, so when colleague - and fiancé - Jim arrives to get her back to the western sector of Berlin, he has to watch his back.
