In "Planet des Schreckens," Valérian, Laureline, and two scientists investigate a mysterious planet split into four distinct zones—each altering human biology in extreme ways: one speeds up aging, another reverses it, a third expands the body, and the fourth shrinks it. Before long, their scientific curiosity turns into a personal ordeal as they find themselves unwittingly tested by the planet’s strange forces.
