It follows Alison (Luther's Ruth Wilson), a young woman waiting tables at a popular Hamptons diner, trying to piece her life back together following a tragedy. After meeting aspiring writer, Noah (Downton Abbey's Dominic West), who is vacationing at his in-laws' estate, the pair embark on an illicit affair.

The synopsis continues: "Alison's husband Cole (Dawson's Creek's Joshua Jackson), struggles to keep it all together, both with his wife and the financially-strained ranch that has been in his family for generations. 

"Their emotionally-charged marriage becomes even more complicated when Alison begins an affair with Noah, a New York City public school teacher and aspiring novelist who is spending the summer at his in-laws' estate out on the island. Maura Tierney (Liar Liar) plays Helen, Noah's college sweetheart, best friend, mother of his children, lover and wife of 17 years."
