The rift

An old ally alerts the Nightstalkers to a resurgence of Rifts in Tennessee, near one of the team's first major skirmishes with the seemingly inexhaustible threat. Though still licking their wounds from their latest mission, the Nightstalkers know there's no one else remotely prepared to battle these intrusions into our world. And this time, they're intent on closing down the Rifts once and for all. But to do so, they'll have to finally face the truth behind the Rifts' origins.
