Ellie Marlowe, a neurodiverse small-town theater owner with Tourette syndrome, is delighted when her latest production sells out. But when the male lead drops dead - and everyone in the cast seems to be a potential suspect or next victim - she must help catch a killer before they pull another show-stopping murder.

The new production at Ellie Marlowe’s community theater could save her from financial ruin, but her overbearing lead, Reginald Thornton IV, is determined to antagonize every cast member. Nervous and with her Tourette’s syndrome flaring, Ellie is relieved when opening night seems to be going well - but then Reginald’s death scene turns out to be all too real.

The state police write the death off as a heart attack, but several things that don’t add up - and Ellie and her childhood friend, Bill Starlin, the local chief of police, begin investigating. When another person linked to the theater is attacked, they’re convinced a killer is on the loose.

As Ellie and Bill discover connections between cast members, they uncover dark secrets and must race to find the killer before it’s curtains for someone else.
