In this thriller, an investigative reporter and a clandestine agent work together to thwart a diabolical plan using ELF waves to take over the world.

It is 1981 when college student Kevin Sommers winds up dead under mysterious circumstances in Michigan's Upper Peninsula. His sister Terri, an investigative reporter from Chicago, arrives in Marquette, Michigan, to begin looking into his death. She is sure that something is not right, she has no idea how correct she is.

Terri learns that Kevin was researching the effects of extremely low frequency waves--also called ELF waves--on people and the environment. What's more, she discovers that the navy was testing ways to communicate with its submarines using ELF. But Kevin's research reveals that ELF waves can affect people's minds, causing unusual and violent behavior. Meanwhile, Terri encounters Clayton Wolfe, a secret agent with a mysterious past who teams up with her and the local coroner and sheriff to investigate Kevin's death. Terri and Clayton feel drawn to each other, but as ELF-induced violence begins to occur all around them, they must race against the clock to find the culprits before they become victims as well.
