This 2005 movie is centered around Dan Reilly, an Irish cattle farmer.
Reilly is approached by a bio-genetics company who want his cows for experiments that make the animals grow faster. The experiments don’t go as planned and one of the farmer’s cows gives birth to a calf that is pregnant with six fetuses. Each fetus has fangs and exoskeletons.
One fetus escapes, and scientists learn its bite can harm animals and humans, which could cause a global outbreak of bloodthirsty creatures.
