Summary

With most of NCIS away and the mainframe shut down for a midnight upgrade, Kasie and a skeleton crew are left in a darkened building when someone begins hunting from inside. What starts as a routine reboot becomes a high-stakes game of cat and mouse through powerless hallways until an unexpected ally, Sam Hanna, steps into the fight.
