Leon and Claire feel like themselves, not fan fiction versions rebuilt for anime. The four episodes move fast enough that you don't notice the plot is predictable until it's over. Beautiful character work and solid action carry you through a story you've seen before, which is enough if you're already invested in these two.

After someone gains unauthorized access to secret Presidential files on the White House network in 2006, federal agent Leon S. Kennedy is called in to investigate. When the power fails, zombies appear, and Leon and a SWAT team are forced to fight them off. Elsewhere, TerraSave worker Claire Redfield is helping refugees abroad when she comes across a boy's drawing that seems to depict someone infected by a virus. Troubled by it, she starts looking into it herself. The following morning she visits the White House to ask for a welfare facility to be built, runs into Leon and shows him the picture. Leon appears to sense a connection to the White House outbreak but tells her there is none. Six years earlier, an American special operations unit sent to a downed helicopter in the Penamstan Civil War found its men turned into zombies, and the incident was classified. Claire's discoveries point to a wide cover-up of bioweapon use, and the two outbreaks prove to be linked. The result is a four-episode action horror ONA with a science fiction edge.
