In the Mediterranean, a place that is both real and fictional. Where Icarus jumped from and burned his wings. Where liners, fishermen, migrants fleeing disaster, rescuers and scientists studying the consequences of global warming on the sea bed meet.

What would Euclid and Thales say about the rising seas? How would they judge our cynicism?
