It's up to the elite crew of the Enterprise to stop the Sackers from using a new scientific device before it destroys the universe!
The Sackers. In all Captain James T. Kirk's travels, he has never found a race more universally shunned and abhorred. Their mere appearance causes most Federation members to become violently ill.
Now the Sackers have performed a deed whose brutality matches their horrifying exterior. They have stolen a revolutionary new scientific device—murdering an entire race in the process—and used it to create a rip in the fabric of space, a hole through which another universe is rapidly leaking. Unless Captain Kirk and the crew of the Enterprise can find a way to stop the new universe's expansion, it will consume—and utterly destroy—our own.
