The episode opens with a tour bus being taken around the new Atomic Station in Australia that is reclaiming the desert. The reporters are not convinced of the safety of the project due to the risk of a nuclear explosion. Meanwhile the Hood is trying to discover the secret of the plant but is caught by security. In the ensuing gunfight, the Hood accidentally hits a gas pump and it explodes. The fire rapidly spreads through the station and soon the staff have to evacuate. The only thing that could have saved them would be to cut off the seawater intake. The plant explodes and sends a radioactive cloud towards Melbourne. But about a week later the wind pushes the cloud back into the desert.
