Continuity mistake: In the scene after Rae discovers being chained her top changes positions on her shoulder between the shots.
Plot hole: Ronnie is shown returning to town a few days after leaving for deployment due to being discharged from the National Guard for his anxiety disorder. In reality, being medically discharged could take weeks, if not months depending on how long it takes the Army to make a decision. If the Army suspected he lied about not having anxiety in order to enlist that could add even more time for an investigation and possible criminal charges for fraudulent enlistment.
Continuity mistake: At the beginning, when Ronnie leaves Rae, her shirt changes position on her left shoulder. The positions change back and forth between the shots.
Revealing mistake: When Lazarus is performing in the bar, Rae takes a drink from an empty beer bottle twice.
