From the YouTube notes:
"Lover" tells a story very rarely told: of the loss endured by partners of gay servicemembers who are killed in battle.
The video features Tom Goss as the bereaved partner of an army soldier (DC actor Ben Horen) killed while on duty in Afghanistan. Among those playing medics who come to the aid of the wounded soldier are several former servicemembers who were discharged under the military's "don't ask, don't tell" policy: Mike Almy, David Hall, and Danny Hernandez, all of whom are active members of SLDN. Keith Bryant stars as a fellow soldier.
The video, Goss's fourth, was filmed in DC and Alexandria. is being directed by DC residents Aram Vartian and Michael Key of DC; Dylan Comstock is director of photography."
