A researcher at Chicago`s National History Museum returns from South
America with some crates containing his findings. When the crates arrive at
the museum without the owner there appears to be very little inside.
However, police discover gruesome murders on the cargo ship that brought
the crates to the US and then another murder in the museum itself.
Investigating the murders is Lt. Vincent D'Agosta who enlists the help of Dr.
Margo Green at the museum - she has taken an interest in the contents of
her colleague`s crates. Unknown to both there is a large creature roaming
the
museum which is gearing itself up for a benefit reception which the city`s
mayor is to attend.
