The MAX rumbles through the opening shot of James Sweeney's new Portland-set psychological dramedy, Twinless. The train clears to reveal an empty restaurant. It's quiet, but forebodingly quiet- almost peaceful. Soon, the city swells into a bustling yet pointedly isolating backdrop for this black comedy about two grieving young men who bond in a support group for those who have lost a twin. This tranquility won't last.
