Tri-School Productions performed their fall play “Clue” on October 18 and 19 and will showcase their last two shows on October 25 and 26. Consisting of students from Mercy B, NDB and Serra HS, the cast had been diligently preparing by memorizing lines and acting out scenes while the stage crew was tasked with designing backdrops and recognizing cues for when to add or remove pieces of the set between scenes.
