Okay, second crack at it:
An Iraqi war vet, who thought he was born American, is betrayed by an ICE agent and deported to Guatemala where he embarks on a harrowing journey determined to return back to the US to reunite with his family and earn citizenship.
(The deportation segment of the script is based on the story of a vet I interviewed for another project who did not know he was born outside the US. He was swept up in a raid and put in for rapid deportation so he could not testify. He filed suit from Mexico and has recently returned to the US. Prior to 9/11, the databases contained a large number of fake social security numbers that were not detected by the military when he enlisted. More than 1500 undocumented Iraqi and Afghan war vets have been deported to date. )
