Grandpa Steiner offends everyone. He doesn't mean to. It just happens. During his youth, his attitudes were commonplace and perfectly acceptable. As the conventions of society change around him, and more and more of his opinions become derided as obsolete, Grandpa Steiner decides to start a blog, to vent his frustrations upon the Internet. Little does Grandpa Steiner know, when a race of space aliens secretly decide to obliterate mankind, they regard his blog as the only redeeming quality of humanity. Grandpa Steiner inadvertently causes the aliens to reconsider, thereby sparing the world from annihilation. But when his popular essays cause a media backlash and his family convinces Grandpa Steiner to stop his politically incorrect rants, will the prevailing ""culture of damn sissies"" spell doom for the Earth?
