‘On Clover Road’ at American Blues: Missing girl, frantic mom; only this stranger can help

Review: Kate Hunter is terrified, desperate, hanging on by her fingernails. Her adolescent daughter ran away three years ago, and finally Kate has a lead to the girl’s seclusion in a cult – even a glimmer of hope that on this day, all may end well. That’s why, in Steven Dietz’s thriller “On Clover Road,” we find Kate holed up in a dilapidated motel room with a brusque, imperious de-programmer who claims he’s experienced at reeling kids back from the abyss. It’s a heart-stopping encounter at American Blues Theater. ★★★★
