Development. Hotels, spas, Nando’s, boutiques. Belfast is changing, but for some people, progress means new barriers.
A group of construction workers is building an extension to the Peace Wall that separates Them-ens from Us-ens. When Polish worker ri’s daughter starts having serious problems with her boyfriend, they rally round in support. But good intentions can easily go too far…
Shibboleth premiered at the Abbey Theatre, Dublin, as part of the 2015 Dublin Theatre Festival
