IT'S A ZOO OUT THERE!

When an elephant runs amok in Idaho, Agent Fox Mulder picks up the scent of aliens at work - and takes his partner Dana Scully with him on a trail that gets hotter at every savage twist and startling turnabout.

The trail leads them to a tiger that melts through iron bars to spread terror with tooth and claw. To a gorilla that tries to reveal the hidden horror haunting the local zoo. And to the dark secrets of those who tend the animals - for their own deadly purposes.

The cage doors of doom are swinging open - to a sinister safari from outer space. Can Mulder and Scully stop it? Or will they themselves become its prey?
