We’ve all dreamed of trading lives with someone else, to escape the monotony of the everyday or to run away from our responsibilities. Home exchanges, where individuals switch lifestyles for a brief period, can be the perfect way to try out a whole different existence. But what happens when it goes horribly wrong? Netflix’s twisted upcoming psychological thriller A Couple Of Lies centres around a picture-perfect house swap between two couples that turns devastating.

The four-part series follows Helene (Frida Gustavsson) and Carl (Fares Fares) who swap their swanky Stockholm archipelago home for a sun-soaked villa in search of a taste of la dolce vita in Sicily. But things quickly turn sour when the police come knocking and dark secrets surface. The couple realise there’s only so far you can run from reality.

With the series arriving on Netflix this week, here’s everything you need to know about A Couple Of Lies, including the plot, cast and how to watch it.

Based on Stefan Ahnhem’s novel of the same name, A Couple Of Lies follows Helene (Frida Gustavsson) and Carl (Fares Fares) who are desperate for some R&R. They swap their home in Stockholm’s archipelago for a stunning hideaway in Italy, owned by a couple they’ve never met – Scarlett (Emma Appleton) and Adam (Jakob Oftebro). Both couples expect a relaxing escape and the chance to reconnect romantically. But their blissful getaway soon becomes nightmarish.

As they settle into their new surroundings, unsettling details begin to emerge. Scarlett discovers a surveillance camera in the swanky riverside kitchen – are they being watched by Helene and Carl? Meanwhile in Italy, police arrive to question Carl about a violent crime that’s taken place. More secrets surface, and tensions escalate as the idyllic retreat warps into a chilling mind-game.

What other psychological thrillers can I watch now?

the girl before
BBC One

For an equally eerie thriller, we’d suggest The Girl Before. The drama follows Jane (Gugu Mbatha-Raw), who moves into a stunning ultra-minimalist home in London, with its own set of strict rules to abide by. Unnerved by her new home, she starts to learn about its chilling past and the woeful fate of the former resident. The question is: will Jane get out before it’s too late? The Girl Before is available to watch now on BBC iPlayer. If you want a twisty thriller to watch now, we’d recommend White Lies. The South African drama takes us to a wealthy Cape Town suburb where journalist Edie (Natalie Dormer) is drawn into a deeply personal story – the murder of her estranged brother. She soon uncovers his dark and seedy past, but she’s not entirely innocent herself. White Lies is available to watch now on Channel 4.
