- At Chicago's Natural History Museum, a bunch of crates arrive from South America, containing some findings from one of the researchers at the museum. The crates arrive with very little inside, and that is deemed suspicious. On the cargo ship that brought the crates, there were 2 murders that took place and a murder inside the museum. Investigating the case is Lt. Vincent D'Agosta, who's a lieutenant with the Chicago Police Dept, and helping him is Dr. Margo Green, who is a researcher at the museum. And somehow, there is a large, massive, gruesome creature lurking in the museum on the eve of a benefit gala the mayor is due to attend. I give this movie a 5 out of 5 star rating, it was totally awesome!
