In the beginning, our three characters meet each other for the first time.
This is Vanessa
This is Connor
And this is Tony
Everyone was stuck in a mental institution. Vanessa cuts herself, Connor suffers depression and at one point shot himself, and Tony's gay (he also drugged himself close to death).
In order to leave, everyone had to "make up" with their parents and prove they were functioning members of society. Everyone was doing well, except Connor, who everyone thought had it all.
After everyone proved they were actually human, they were allowed one final trial: Surviving the wilderness. At this point, after much internal debate, Vanessa hooked up with Tony, who (Plot Twist!) wasn't gay!
While Vanessa and Tony were getting better, Connor got EVEN worse. He decided to stop taking his anti-depressants in order to at least appease his parents that hate him. This was a terrible idea.
In the end, Connor flung himself off a cliff, killing him in front of everyone. Everyone was devastated, but it was left on a "hopeful" note. With Tony and Vanessa as a couple and a paper airplane flying at them.
