but today you swirl and spin
in sea water as if,
creatures of salt and slime
and naked under the sun,
life were a waking dream
and this the only life.
– From ‘A Swim in Co Wicklow’ (2011) by Derek Mahon

In 2012, the Irish long-distance swimmer Stephen Redmond became the first person to complete the Ocean’s Seven challenge, which includes marathon swims in seven channels around the world. In The Swimmer, the Irish filmmaker Thomas Beug takes us along on a brisk Atlantic swim, gracefully weaving lyrical images of Redmond on land and in the water with his musings on the ineffable sense of purpose he finds in the open water. Complementing Redmond’s narration are lines written and performed by the Irish poet Derek Mahon, offering a refreshing glimpse of the sublime and the spiritual within the realm of extreme sports.
