Code

The Virals are put to the ultimate test when they find a geocache containing an ornate puzzle box. Shelton decodes the cipher inside, only to find more tantalizing clues left by "The Gamemaster." A second, greater geocache is within reach — if the Virals are up to the challenge.

But the hunt takes a dark turn when Tory locates the other box — a fake bomb, along with a sinister proposal from The Gamemaster. Now, the real game has begun: another bomb is out there — a real one — and the clock is ticking.
