Meet Hank Atkinson, a biology professor in love. He marries the lovely Susan, and together they live happily for some time. Then, one day while walking to the university, Hank is kicked in the head by a pigeon, stumbles into the street, is hit by a bus, and dies. Susan mourned for a little while, but eventually remarried to a man by the name of Tad Wegman. The end. Or it would be, if months later, Hank didn’t come back from the grave as a zombie, and try to win back his lost love.
