A lonely middle aged autistic man’s painful journey to spread wings and not slip into a made up fantasy world – after beloved parents violently die in a car accident of his doing.

Thanks Nir, looks fine now.

The stakes are "slipping into an fantasy world' or in ohter words "loosing quality of life". jkcantwell suggestion does make a whole lotta sense, but almost every logline I (with the help of this forum) have now starts with "after" or "when" and although it works real well, it's starting to be annoying.

Yes good point how about:
As a result of a car accident a lonely autistic man looses his beloved parents and must now find a friend in order to stop himself from slipping into a made up fantasy world.
