Two self-centred paleontology students cause problems after they put to work a theory and spell found in a 1939 researcher's notes. They bring back a dragon demon via the resurrection of some dinosaur eggs.
The eggs that they thought were Timimus actually were something more like Rex, and they grow fast, and the demon needs four of them. Four Rexes, even baby ones, can eat a lot of people. With a demon controller, even worse.
