Metroland: In late-1970s suburban London, Chris and Marion have settled into a comfortable yet all-too-predictable middle-class existence. Chris receives an unexpected visit from his free-spirited friend Toni, a reunion that reminds him of a more carefree time in 1960s Paris. Now, with lingering doubts about his marriage bubbling up, Chris must make the choice between revisiting his youthful abandon with Toni or facing the here and now with Marion.
