In the middle of London lies Hampstead Heath, 320 hectares of forest and parkland plus three swimming ponds. People swim in them all year round, whatever the weather, just as they did in the time of Keats and Constable. 

Capturing the beauty of the English seasons, co-directors Patrick McLennan and Samuel Smith filmed the swimmers over 12 months as they laughed, sang, complained, ruminated, philosophised or simply sought respite from all that life threw at them. 

“In the nicest possible way, this gentle and forthright film is a kind of home movie, almost a series of hyperlocal video-diary entries, full of uncomplicated happiness in a way that most documentaries aren't.” ★ ★ ★ ★ – PETER BRADSHAW, THE GUARDIAN
