M1 F1. A living-room. It's an unremarkable Tuesday night in October. Jill and Peter Wilson live together in an immaculate Ikea-furnished flat in north-west London. Jill is pregnant. Peter has bought wine and ordered a takeaway pizza. Jill has packed her suitcases and written Peter a letter. As Peter tries to outwit the pizza delivery man to guarantee them a free order, Jill tries to get him to attend to the more pressing matter of her imminent departure.
