Two climbers see the ISA from Everest's peak and decide the moon is next. That simple promise, two guys chasing the same dream through different doors, powers everything that follows. The show trusts you to care about the climb itself, not tragic backstories or philosophical weight. Gorou and Jack are good at what they do, charismatic enough to carry a room, shallow enough that you're never waiting for them to become someone else. You're here for the momentum, the next contract, the next obstacle between them and the black. It doesn't apologize for being exactly what it advertises: two men in a race to space, and you're running alongside them the whole way.

After reaching the summit of Mount Everest, climbing partners Gorou Saruwatari and Jack F. Woodbridge, known as "Lostman", catch sight of the ISA Space Station, and each of them swears he will one day travel into space. When Helium 3, a promising new source of energy, turns up on the moon, NASA sets up a program called Nexus to bring that power back for use on Earth. The story traces the separate routes the two men take as they chase their dream, bound up in the push to tap this next-generation fuel. The twelve episodes of this TV season blend adventure, drama and science fiction.
