The closest of schoolfriends in 1989, despite their wildly contrasting personalities, risk-averse introvert Blandine (Olivia Côte) and gobby showoff Magalie (Laure Calamy) fell out spectacularly (full details are hazy, but it involved a boy) and lost touch. Now, thanks to the adult son of Blandine, who worries that his divorced mother is in danger of closing herself off from the world, the pair are reunited and find themselves embarking on the trip they dreamed of as teenagers: to the Greek island of Amorgos, location of the film The Big Blue. Except that, owing to erratic nightmare Magalie, they are kicked off the ferry for fare-dodging on to another island.

Two Tickets to Greece has some appeal: stunning scenery, Instagrammable taverna chic and the unexpected pleasure of seeing a cast-against-type Kristin Scott Thomas letting her hair down as a boho jewellery designer. But the character of Magalie is so enraging that you would chuck yourself into the Aegean Sea rather than spend two weeks in her company.
