Mark Sowerby battles bad feelings by tackling brutal channel crossings – the Oceans Seven – around the world

The title of this invigorating documentary about open-water swimming seems at first to be a wry note-to-self regarding something competitors essentially have no control over: the possibility of becoming shark food. But, as practised by Australian waterman Mark Sowerby, it turns out to a surprisingly deep and empowering maxim about choosing to accept apprehensions and fears, and not being picked off by one’s inner vulnerabilities.

Sowerby is that oft-spotted species: the investment banker seeking redemption. Adrift among the 1%, he pivots to long-distance swimming and makes a traumatic crossing of the English Channel in 2015. Then his company becomes chum for short-sellers. His self-esteem in tatters, depression swallows him up. Realising he can process the trauma with intensive pool time, Sowerby decides that completing the other six stages of the “Oceans Seven” – a set of brutal channel crossings around the globe – is the tonic he needs.
