Once I Was a Beehive (2015) on Netflix

Lane Speer is a 16 year old girl who spends her family vacations camping in the mountains. She takes the memories for granted until she loses her father to a bout with cancer. Only a year later, as Lane is still reeling from her father's death, her mother marries a guy that Lane hardly knows. Worst of all, he is a Mormon. To top it off, while they are on their honeymoon, they arrange to have her stay with her Mormon step-aunt who takes her away to a bible-themed girls camp with a bunch of young Mormon girls. Confronted with memories of camping with her family, she tries to find peace with her new surroundings and deal with the death of her father.
