The film involves two married couples: Nick and Charlotte and Luis and Eva.

Nick and Charlotte are more than busy earning money, there is no time for love or sex - only Tuesdays.

During their stay in Venice, Luis becomes ill and spends the entire week in the bathroom.

On their way from Munich, Germany (where the first half of the story takes place) to Venice, Eva's car breaks down somewhere in the Alps, so she, Nick, and her two children are forced to walk and hitchhike the rest of the way.

They arrive in Venice without money, passports, credit cards, their clothes torn and burnt, on a Friday evening, which means that they have to spend the weekend without any support from the German consulate.
