On a university campus where most students are out for summer vacation, five students sneak into the library storage to look for treasure. What they find are two sets of female antique mummies from Italy. One of the members, Sayaka rips open one of the mummies and takes out a stone, empowering the mummies to have super strength and eternal life. Having stolen their “stone of life”, the two mummies awaken and ferociously attempt to retrieve what was once theirs. The only way for the students to escape this situation is to find a way to kill the zombie girls… but will they be able to survive?
