For the past twelve months, the whole world has been in a precarious position due to the outbreak of a dangerous virus. It appeared suddenly and spread so quickly that some countries failed to take the necessary measures in time and protect the population. The first weeks of humanity seemed to be paused. In most states, strict quarantine was introduced, which forbade going out even for groceries. Only scientists worked tirelessly in laboratories, trying to create a vaccine and prevent the death of people. Over time, severe restrictions were lifted. Vaccines have been freely available. The world started to move again: cafes and subways opened, it became possible to fly on planes to different countries. The only condition left is the wearing of masks in public places. Jim and Kat easily survived the epidemic. They spent all this time at home, enjoying the kisses and hugs of a loved one. When the worst was over, they returned to work. But suddenly the world was shocked by the news about the mutation of the virus. His new strain is incredibly contagious and is expressed in increased aggression. Jim and Kat were among a large crowd when the first infected appeared there. And it would be a real miracle if they managed to get home this evening.
