THE PLOT

The Deep Ocean Driller, the world's largest oceanographic vessel, is off the Yucatan Peninsula. On board is Professor Basalto, a geologist who is investigating whether a meteorite that fell in this area was the cause of the extinction of the dinosaurs. The ship has a system of tubes that reach the seabed to drill it and extract clay samples that will later be analyzed by scientists. Aunt Abi is there doing a report, accompanied by Simón, Lucas, Isabel and Juana. Unexpectedly, things get complicated when one of the drilling tubes, which has radioactive material at its tip, gets stuck and causes a serious accident that puts the entire mission at risk. The boys' recursion will be final to solve the emergency and save the underwater sediment sample that contains the key to understanding why the largest creatures that inhabited the Earth ceased to exist 65 million years ago.
