In Cape Verde, in a very isolated fishing village long cut off from the world, a man survives from day to day by eating shells that he fishes with flintstones along the rocky coast, a dangerous and difficult activity. Hustled by the swell of the ocean and bathed in the mist of the sea spray, he fishes with a childhood friend, a woman who fears nothing. They both live in precarious conditions. They struggle to get by and hope their situation will improve thanks to the tourism development that is underway. They are looking for a way to benefit from the influx of tourists who are coming to their village in ever increasing numbers to trek and fish for blue marlin, the "cheetah of the seas".
