The year is 2250, technology and dream vaccination are quite advanced... A simulation laboratory has been established where people can choose the dream they want and live it, and feel it personally. People are offered the opportunity to fly, became famous, live like an animal and set a dream that they can achieve only by dreaming. While everything is going in its normal order, the users are stuck in their dreams and experts, who realise this system error, understand that a virus enters the users' dreams and kills them unexpectedly. A virus appears as a character which is suitable for everyone’s dreams and poses a great danger.
