An exciting space action movie in the best traditions of Starship Troopers. Distant future. The space fleet is the shield and support of the Earth and its Colonies, the fighting elite. The rest of the troops are nothing more than screws on this shield. Vitaly Shebaldin is a brilliant graduate of the Space Fleet Academy. His future seems cloudless: service in the elite troops, a successful career, the romance of deep space. However, his grandiose plans are not destined to come true, because he is destined only for the dreary fate of a “screw” - a quartermaster on a spaceship. However, it is very likely that this is not the end of the adventure, but only the beginning - after all, fortune is changeable and such information may fall into the hands of the “screw” on which the very existence of the Earth will depend.
