Siska Deluxe is a story about three male childhood friends who are not quite so young anymore but cannot seem to grow up completely. They are full of business ideas but since neither of them ever commits seriously, all of their plans ultimately fall through. When the aunt of one of them dies, she leaves him a small commercial property and the three friends immediately decide to open a pizzeria. In the beginning, it seems as if this is another project doomed to fail. However, just in the nick of time, an unusual woman named Jana comes along and offers to help. There is another curious character, Sale, who seems to be the friends' arch enemy, but is ultimately transformed to their closest and most trusted friend. With the close weaving of the comical with the dramatic, the light-hearted story never questions the possibility of a happy ending.
