The architect Stefan Hellwig is to plan the construction of a housing estate for a hard stone factory in Tyrol. As his landlord Meier from Dortmund is on his way to Africa with his family, he gets a cheap ride to Tyrol. There, the Meiers are initially forced to make a stopover because their daughter Babsi is weak. While they finally abandon their plans for Africa to spend their vacation in Tyrol, the budding romance between Stefan and the local vet Karin seems to come to an abrupt end when she finds out why he is in Tyrol.
