No this is not a plot from a movie.
Three men have been rescued from an uninhabited Pacific island after writing S-O-S in the sand.
They'd been missing in the Micronesia archipelago for nearly three days when their distress signal was spotted, Sky News reports.
They ran into trouble when the boat they were travelling in sailed off course and ran out of fuel.
Captain Terry Morrison, Canberra's commanding officer, said: "I am proud of the response and professionalism of all on board as we fulfil our obligation to contribute to the safety of life at sea wherever we are in the world."
All three men were said to be in good condition, with an Australian military helicopter able to land on the beach and give them food and water.
