The Silver Vampire Rhamphorhynchus

An accident in an illegal science lab in Africa leads to the spread of an infection whereby humans and animals transform into birdlike and other animal-like creatures with glowing blue blood when bitten by those infected before them. The CIA enlists the help of the Silver Vampire, who, along with an entire sheriffs team, come to Africa to start a battle against the infected animals and humans. Even dangerous was that if the Silver Vampire got infected, the other vampires would die too. No one in the African government or the CIA know about the agents secretly working in Africa. Sarah, the vampire CIA agent, must work underground with all Americans in Africa until the infection is contained.
