It’s drizzling and it should be snowing by now. The Pilsen Advent Market is in full swing. The Javořičky children’s choir is preparing for a carol singing, and hot wine smells all over the square. The baker couple at the cake stall are probably splitting up again. Otherwise, there is a calmness here, complicated only by the approaching Czech Trade Inspection inspectors. But the routine of tradition, folklore and Christmas business is definitely disturbed by a bag that has been left behind and something is ticking. Someone should do something about it. Who will it be? Lada from mistletoe, Mrs. Jiřina from potato spirals, or Marek with funny mugs? And how many other bags are actually ticking? The short Christmas film Bomba is the feature debut of documentary filmmaker Vit Klusak.
