The U.S. Government tests a new device that harvests energy from the sun, stores it in a satellite, then can target the energy at other satellites or missiles. However, it malfunctions and sends the energy back to the sun, causing a huge solar flare which causes hundreds of satellites to fall to Earth. London is badly hit and downtown Chicago destroyed. A scientist (Matthew Modine) realizes what is happening and tries to help, along with the assistance of his former partner (Maxim Roy of ReGENESIS) who is partially responsible for the crisis to begin with.
In the first half of this mini-series, the scientist manages to save the Earth by reconfiguring the device, which shields the planet from a radioactive blast that would destroy the atmosphere. What thanks does he get for this? He's taken prisoner by the secretary of defense, who has a grudge against him. But then a problem happens with the magnetosphere--the Earth's molten core has stopped spinning. If it's not started the world will die within the week. So in the second half of the series he has to try to restart the core, with the help of his family, while the army tries to stop them.
This is a decent disaster flick, similar to RING OF FIRE and FLOOD, and reminded me of the Irwin Allen epics of the 70's. Recommended.
