The Marines Rokot, Struna and Boika were blown up by mines during the fighting and were seriously injured. Each of them lost a leg, but they did not lose their strength of spirit and sense of humor. "What is it, how to manage it?" Struna asks, having received the prosthesis. The heroes learn to walk again, maintain their combat form at the training ground, and are assisted in this by a prosthetic technician, Ibrahim, who himself lost his leg 12 years ago during a terrorist attack in Stavropol.
