Bellmouth (2018)

Amy is taken on a impromptu camping trip by her Dad on her 15th Birthday. Amy's enjoys the the endless summer days, campfire nights and long wandering walks through rural south Devon. As time passes and days turn into weeks, the junk food runs out, the campsite becomes a muddy rubbish dump and the dad's naive optimism gives way to growing fear. The girl's creeping suspicion is that something isn't right. It falls to the girl to gather the strength to find some food, look after her little brother and finally confront her dad to ask why they can't go home. Amy makes the decision that it is best for her and her brother to leave the camp, with or without her Dad.
