On the trail of a missing friend who had been experimenting with mind-altering drugs, a young journalist - aided by a rogue counter-culture writer, finds herself drawn into the dangerous world of top-secret government chemical research and the mystery of a disturbing radio signal of unknown origin.

During a solo voyage in the Indian Ocean, a veteran mariner awakes to find his vessel taking on water after a collision with a stray shipping container. With his radio and navigation equipment disabled, he sails unknowingly into a violent storm and barely escapes with his life. With any luck, the ocean currents may carry him into a shipping lane -- but, with supplies dwindling and the sharks circling, the sailor is forced to face his own mortality.
