Long time building resident, Gillie (SHIRLEY BENNETT) shares support and gossip with new-in-town tenant, Mara (DORI O'DEA) in 'The Sentinel,' a half-hour drama by New Jersey playwright Hal Corley which asks audiences to consider the uncomfortable superimposition of old time neighborhood values onto de rigeur measures to ensure self-preservation in a world of suicide and stalkers. Troupe member Emily Lord makes her directorial debut in this Petaluma Radio Players production.
