FAT KATHY

Warsaw's water treatment infrastructure is home to a fascinating microcosm: clams from nearby lakes serve here as an early warning system in case of contamination within the central pumping station, like tiny unsung heroes of the Polish capital. Alas, the aquatic protectors are defenceless subjects themselves, though looked after with loving care by their hosts. With a calm touch and a curious eye, this film tells the story of an unusual symbiotic relationship between human and mollusc.
