Their quest leads them to some of the world’s most remote caves, both above and below the water, in France, Iceland, the Bahamas, the U.S. and Mexico’s Yucatan Peninsula. Together, they go where very few humans will ever go, revealing the incredible lengths scientists will go to study the unknown.

With the villagers of Saint-Élie-de-Caxton barely having enough food to survive, Ésimésac convinces them to collaborate on a community garden.

Riopel, the hulking blacksmith, starts working on the railway track and convinces the locals to invest in his project rather than waste their time playing in the garden. Ésimésac’s big project flounders under the weight of metal. But can he really stop progress?
