It was one big old culture shock for Mark DeCarlo and his family in Mobsters and Mormons. The cheerful hit-man who has run afoul of his former associates is now in witness protection. But what a place they've relocated him to. A small town in Utah where 98% of the populace is of the LDS church. The man just can't relate to those folks although at least one neighboring family headed by Scott Christopher does their best to make him feel at home.
These folks operate on a whole set of different values than DeCarlo's been brought up to believe. And poor DeCarlo can't get a decent pizza and his craving for real coffee nearly gets him and his family killed.
It's an interesting idea for a comedy, but sadly lacking verisimilitude. Witness protection has had almost as many failures as successes. The most notable example of that was Sammy 'the Bull' Gravano who while in witness protection got involved in a few local rackets of his own creation. Those folks don't think like most of us relatively normal gentiles let alone those of the LDS faith. It's a gulf of the minds I think is almost impossible to cross.
Still Mobsters And Mormons has a few good moments, my favorite is DeCarlo giving some young kids the gangland New Jersey version of the Three Little Pigs. I wish the film had more moments like those.
