Close Encounters of the 4th Kind: Infestation from Mars (2004)

A covert military effort is made to bring back a sample of germ-ridden Martian soil, in order to develop the ultimate biological weapon of mass destruction. A solar flare knocks the returning probe off-course, where it crashes on a farm in Sandusky, Ohio. An innocent by-stander becomes infected with the germs, and turns into a murderous alien hybrid killing machine.
