Violent Quarantine Zone

The high walls are covered with circles of barbed wire. Inside the walls live a group of faces with dull eyes, no words, and stiff actions. Some of these people wear gas masks, and some are secretly exchanging information. People wearing gas masks are always coming in and out of a building labeled EF Research Institute. The building is heavily guarded, with security personnel wearing special clothing and carrying explosion-proof equipment. Researchers inside the building are developing the EF virus to evolve humans, and a conspiracy and escape are quietly unfolding.
