Hello, School,
I'm not sure who the audience is, nor the puropose of the communication. Assuming this is a synopsis of a movie or book, and that the purpose is to build awarenesss of an interesting topic of rreading/viiewing, I wroite the following:
------
The life of Desmond Doss, a heroic survivor of WW2 who was awarded the Congressional Medal of Honor for his bravery in saving 75 men at the Hacksaw Ridge battle on Okinawa, does not follow an expected trajectory. His tumultous childhood in a dysfunctional family and alcoholic father, a WW1 veteran, marks his story as unique.
-------
Not great, but maybe there's an idea here you can use to get it right.
Bob
