Various Londeners meet people in Hampstead Heath park. Financial adviser Billy (Ewan McGregor), a successful casual sex seeker, discusses the pros, cons, and how of his child-wish. Cheeky Noel's (Tom Hardy's) innocent pick-up lines lead only to cruelty from girls, once even abandoned jeans on ankles. Gerry's (Hugh Bonneville's) promising blind date picnic ends as abruptly when his business partner turns up, who just agreed to a Barbados holiday with his steady girl. Eddie (Benjamin Whitrow) discovers through a date mix-up that Iris (Dame Eileen Atkins), his ripe age, who come to the same park weekly too, but a day earlier, was his prospective mate until they each met their now late partners several decades ago. Pete (Adrian Lester) comes to settle the end of a marriage that shouldn't have happened except for his daughter.—KGF Vissers
