Hydra is one of the Argo-Saronic Gulf Islands of Greece.
The settlement of Hydra is built on two rocky hills, amphitheatrically around the port.
At the beginning of the film, we watch the course of a sailing boat in the Saronic Gulf.
Afterwards, we are on the rocks in front of the Nautical Club of Hydra (formerly Lagoudera) and we see a crowd of swimmers as well as members of the filmmaker's group of friends, diving with excellent technique and a spectacular way, enjoying the wonderful waters.
