Stacey travels to Preston to spend time with a family who have encouraged their teenage son, Kyle, in his amateur career as an MMA cage fighter since the age of four.

The Preston family from Ashton-under-Lyne are members of the Jesus Christ Church of the Latter-day Saints, or more commonly known as Mormons.
