On-the-run romcom with a dark twist

When bored housewife Ruby (Merritt Wever) receives a text from her ex, Billy (Domhnall Gleeson), saying ‘RUN’, she abandons her family, meets him at Grand Central Station and takes off across America with him, as per their pact made years ago at college. So that’s bound to go well, right? The show starts out as a zany romcom but, as the details of the lives they are running from are gradually revealed, it becomes darker in tone. It’s written by Vicky Jones, creative partner of Phoebe Waller-Bridge, who appears as a mysterious roadkill taxidermist. Sky/NOW TV, available now
