Unseen: Long Way Home

In Los Angeles, Angel and Buffy compares notes and realize that both of them are dealing with cases of missing teenagers - most of them are children of the rich and powerful. Coincidence? They don't think so. But when Buffy checks in with Giles, she learns that prime time doomsday has hit Sunnydale, taking precedence over the gang warfare in LA. Back in Sunnydale, Buffy finds the gateway through which the monsters are gaining all access passes to our universe. These gateways are controlled by renegade scientists who have discovered how to manipulate time and dimensional portals from one reality to the next, which could explain where the teens are hidden. But something goes wrong and nothing ever comes out of these gateways the same way that they went in. Now they come out bent and destroyed. Alina is the only child that can control these portals but either she's lost her control or something in the Hellmouth is breaking these barriers. Buffy and Angel must go into the portal and see if they can salvage any of the children left on the inside.
