Odd couple Jack and Julie uproot from the French backwoods to settle, during the stifling heat of summer, in a rundown Paris tenement. All the better to allow the sullen Jack via his job driving a taxi at night to make an honest franc, and enough to keep these two passionate lovers in takeaway pizzas, consumed during the brief time-outs they take from their marathon bonking sessions. So much time do they spend en sac, in fact, that they have absolutely no social intercourse with the outside world and thus the seemingly earth-shattering event of a third character entering their lives Joseph, Jack's fellow cabbie who drives the day shift sends Julie spinning off the rails. And, before you can yell Up Yours Delors, she is merrily indulging in a spot of how's-your-father by night with the brooding Joseph, and yes by day with the unsuspecting Jack.
The theme of menage a trois is, of course, a staple of French cinema, and though the subject matter generally tends towards intensity and claustrophobia, Night And Day's moments of wry humour such as when Jack's parents visit the apartment, coitus interrupting and its brevity overcome the film's lack of dimension. When a ridiculously jolly Julie, cheerily grinning throughout, is, however, forced to make a choice between this pair of angst-ridden deadbeats, you can't really blame her for taking off before a nasty case of bed sores sets in.
