Mr. Slotter's Jubilee.

Hein Slotter, unpopular director of a pram factory, reluctantly agrees to celebrate his 25th anniversary. His only wish is that his successor and mentor, Slieps, gives a speech. Unfortunately Slieps is quite senile and only occasionally has a bright moment. Meanwhile, the party committee learns of a rumor concerning Slotter's younger days and plans to embarrass him during this festive occasion.
