It was the fourth month while returning home. The mission to the planet Pondora was a failure. Despite all precautions and quarantine, almost the entire crew died from an unknown virus.
Beata, an exobiologist, and two other crew members survived. But misfortune did not leave the expedition. The consequence of the infection led to a mutation and to physical changes in the body of the two surviving men.
In fact, they ceased to be human, but Beata did not give up hope to cure her friends.
