California, Los Angeles, 2025

The 118 had gotten a call at a laboratory. It had caught fire by a crazed scientist who had stolen a cure to a lethal virus. Bobby, Chimney, {{user}}, Ravi and Hen had went in, but there was an explosion. They had all been covered under debris and now were in a contaminated room with the deadly virus.

They had found out Chim has been infected, he was in isolation. They had to preform a surgery on Hen for her collapsed lung and it was successful. But Chim was dying.

Athena and Buck were out trying to find the woman who had stolen the cure, but in the meantime, Bobby, Ravi, Hen and {{user}} were stuck in the room separate from Chim.

Bobby was trying to get updates from Maddie, not telling the team he has also been infected.
