Casper Van Dien,
Ernie Hudson, Jenny McShane and Bentley Mitchum star in this thriller about a marine biologist doing research at a facility off the coast of Africa. Hammerhead sharks have long been a presence to be respected in local waters, but now they've started attacking people without reason -- apparently for fun. While superstitious locals fear demonic possession is to blame, the biologist thinks this may be the results of experiments performed by a former colleague turned rival. ~ Mark Deming, All Movie Guide
