Queen Latifah and Dolly Parton star in this "Glee" for older, straighter people. The two singers/actors appear as members of a small-town Southern church choir who scrap over how best to lead their team to a national singing competition. Can they "give their all to win God's praise and beat the competition for the grand prize"? If you loved Sister Act 3, you'll be in Heaven with this one. 117 minutes PG-13.
