'The Professor is married to Hazel, a diligent and generous (but rather plain) woman. She is so close to her twin, Chloe, that both women live under one roof with the Professor.
'Back from an overseas trip come their daughters — triplets — ready to celebrate their twenty-first birthday. Family life in the otherwise peaceful house swells to a chaotic crescendo on the evening of the party, as the Professor feels the tender sting of his wife's accommodating ways.'
