After losing the next set of coordinates, the team is forced to chase after the Phantom in a desperate attempt to retrieve the next vial of serum before he can get to it.

But all of that seems to pale in comparison to a new discovery that the Radiation Serum Device alerts them to: not a serum signature, but something big, and entirely different.
