When amateur sleuths Hattie Collier, Bea Bell and Connie Palmer, win a trip to Las Vegas, they decide that crime solving can take a holiday. It’s fun in the sun for the adventurous widows, and Hattie’s cantankerous mother-in-law, Miss Fanny—that is until the devil’s playground proves too much for Hattie. She is sure that her two friends are headed straight to hell and with her mother-in-law hitting the Vega casinos like a pro, what is a God-fearing grandmother to do? In the process of saving her friends and Sin City from the gates of hell, she raids a strip joint, causes a street riot, is tossed into jail, and becomes the infamous Bible Bomber. Take two fun loving grandmothers and one religious zealot, put them in Las Vegas and the result is a laugh riot called Saving Sin City!
