Let it out

Several teens get a detention one Saturday evening. When the teacher in charge gets called away, the kids decide to sneak out to the local theme park - the only problem is its closed. They end up breaking in but when they find they aren't the only people there the night takes a turn, and as the night end they realise they aren't so different and that secretes can unite people... until you need to let them all out
