Long-standing secrets, adventures and forbidden love - and all this on board an interplanetary space military academy. Having barely recovered from the attack of a mysterious enemy, the Quatra Space Academy, which for centuries accepted only a narrow circle of the elite, finally begins to enroll students from all over the Solar systems. Vesper, a tough pilot who dreams of becoming the captain of a spaceship, suddenly loses in a competition to a sarcastic guy from somewhere in the asteroid belt, and it makes her question everything she has believed in until now. Cormac, who grew up on the toxic planet Deva, is ready to grab any chance to escape his home hole and become a cadet at the academy - even if it means taking someone else's place. Arran, from the ice-covered planet Shetir, dreams of something more than spending the rest of his life working in the mines. And Orelia has a dark secret - she infiltrated the academy to carry out a dangerous mission. And if anyone finds out about her plans, she will definitely be in trouble. But the cadets will have to forget about everything that divides them and unite as a team to confront the insidious enemy.
