A television program on Sunday will, as part of the storyline, depict an endowment session using the "expertise" of a former member of the church to help the set and wardrobe designers depict as accurately and in as much detail as possible the sets and wardrobe. There is an article in the TV Guide with a picture.
It is unfortunate that the shows creators have violated their assurances to the Church that the show would not be about Mormons. It is a reference to their character that they have chosen to depict that which they know is sacred to many people - sacred enough that they had to use as a consultant someone who is disaffected with the church.
