It's been well documented that post-traumatic stress disorder not only affects servicemembers, but also those closest to them.

"Dying City," a play by Christopher Shinn currently running through April 11 at the Bathhouse Theater in Seattle and performed by Seattle Public Theater, examines the relationships surrounding those dealing with PTSD.

The 80-minute play, which was nominated in 2008 for a Pulitzer Prize in drama, offers a look at the fallout of war after a young man deploys, and how his death thousands of miles away has rippling effects on those he leaves behind.

"The big issues surrounding this world are played out in a small space and a very simple story between three very lost souls," director John Vreeke said in a release.

"As a director, the great challenge of the piece is to understand what is unspoken, what the silences contain and how they explode."

The soldier's widow is a therapist who watches "Law and Order" because "the mystery of a death is solved and therefore symbolically reversed." But when her dead husband's twin brother shows up unexpectedly, what she believes to be true is called violently into question.

"It's not a play with a message, it's a play about people," said Shana Bestock, SPT artistic director who also plays the widow in the production. "It raises so many questions - (Vreeke) wants to really challenge the notion of closure."

As a thank you to veterans, active servicemembers and their families for their service to the country, SPT is offering a two for one discount on tickets with the presentation of a military ID. This Sunday's matinee performance will be followed by a post play discussion. The discussion serves as an opportunity to explore issues touched on during the show with the artistic team, Bestock said.

Active servicemembers and veterans are welcome to share about their experiences with PTSD, as it has a chance to provide additional insight about the disorder to other audience members, she said.

"I think it's really good for those without PTSD to listen," Bestock said. "We mostly just want (veterans and servicemembers) to know that others are thinking about their experience."
