Kristen Clark and Bethany Baird are God-loving, God-fearing sisters living together in Texas. They have declared it their mission to share the TRUE words of God with the rest of the world, and do their best to turn everyone into bland, hypocritical, rule-following sheep just like they are.
One of their strongest messages is about marriage, how God designed marriage for one man and one woman forever, and nothing else -- not more than two people, not divorcing after a few years, and especially not two men or two women. In fact, both of them are happily married and their (bland, hypocritical, God-loving, rule-following) husbands live with them, all in the same house as is God's design.
But one day, Bethany discovers some strange feelings that she's been having, and not even the Bible can save her from them.
