Mystery carries a sinister edge in suspenseful drama from Debate Society

The setting of Jacuzzi is a secluded Colorado chalet, where Helene (Hannah Bos) and Eric (Paul Thureen) relax in the sauna as the action begins. Then a caller leaves a phone message suggesting something’s amiss. Dramatic bait has been dropped, and we’re hooked. Bo (Chris Lowell of the movie The Help), a deeply troubled rich 26-year-old whose dad owns the home, arrives. Bo figures that the duo has rented the place and that he’s intruding. But the play keeps you guessing about the nature of the curious twosome whose easy smiles seemingly mask something sinister. Soon Bo’s estranged dad, ­Robert (Peter Friedman), still bitter about his divorce, arrives. He treats Helene and Eric like they’re personal servants. But who’s ­really got the power ­becomes clear as the characters come into somewhat sharper focus.
