A lonely Japanese businessman, a cheating wife, a London hotel and a binge drinking bride-to-be.

After relocating to Tokyo, a Brazilian writer begins a new novel, provoked by her experiences in Japan and by one of the last scenes she witnessed in Rio de Janeiro: a female swimmer tearing up the horizon with powerful strokes in the wide, open sea. Those two women apparently share no connection, until their lives start to interfere in one another, strangely linked through the sea. Hannah, the writer, plunges into a journey of self-discovery in Japan, while Ana, the swimmer in Rio de Janeiro, oddly has her body transformed into some kind of inner Ocean.

Some called it, "enemy attrition at the lowest possible cost, without regard to human life." Entire squadrons of Japanese kamikaze pilots flew straight to their death - taking their enemies with them.
