Cross, replete with a fine brogue, plays a Scottish lawyer who, stood up by some Tinder-ish dude in a Edinburgh wine bar, finds herself sharing her bottle of wine, and then her bed, with Mulvey’s Bob, a petty thief and benign loser for whom this one-night stand just might turn into a kind of salvation. In David Greig and Gordon McIntyre’s tall tale, told by a pair of competing narrators, this most unlikely of couples engages in a variety of capers, careening around one of Europe’s most fabulous cities and running into gangsters, kids and bridesmaids, each more wacky than the last.
