Two cells observed under the microscope. They grow up together and meet many different creatures on their outings. One day they are separated by an accident and it takes a long time before they find each other again. After the first outburst of joy, they realise that they have changed and no longer fit together. A colourful and profound animation.

A shimmering shoal of herrings are swimming through the wide ocean when they are suddenly broken up by seagulls. Separated from the shoal, a small herring ends up all alone in a tidal pool. Looking for a way out, he encounters many other marine creatures. Some scare him. But there’s no time for this now: Only by joining forces can they defend themselves against the hungry seagulls.
