The smartphone that’s become so much a part of your life could kill you. And that’s just what the Karachi group wants. Set in 2015, CELLFIRE traces fictional West Media’s entry – the Wave - into the high-flying smartphone market. Unknown to nearly all, however, an explosive material has been built into the ever-popular device that will be detonated during the Christmas holidays. Seemingly unconnected events, including four murders, have aroused suspicion but it could be too late to defend the latest assault on America. The clock is ticking.
