When August promises thunderstorms and resultant soggy clothes, there’s only one thing for it: brilliant TV – and BBC One’s latest drama, Trust Me, is just the ticket.

Identity theft, A&E and a budding romance: it’s a heady mix in a four-parter that will have you desperate for the next episode.

The show follows the story of dedicated and passionate nurse, Cath Hardacre whose devotion knows no bounds. Concerned about patient care in the cardiology ward in which she works, she whistleblows the department’s shortcomings, only to find herself let go.

A single – and now unemployed – mum with a young daughter to care for, Cath’s panic is assuaged when she comes across some documents in her best friend’s wastepaper basket whilst drunk on champagne.

If you’re not tempted yet, here’s five reasons why you will want to watch it:

Trust Me is Jodie Whittaker’s first role since the announcement that blew up the internet: that she would be the 13^th – and first female – Doctor Who.

Reaching fame as the mourning mother of murdered schoolboy, Danny Latimer in Broadchurch, this is Whittaker’s first leading prime-time role, and she carries it brilliantly. Her visceral depiction of a woman willing to go to any lengths to protect her family keeps viewers firmly on her side whilst she carries out dangerous and life-threatening operations.

And if you’re not already confused by the soon-to-be Doctor Who star playing a nurse pretending to be a doctor, just watch it for the fact that she’s a name to know, ahead of her spin in the Tardis.

Like Working Girl meets Holby City, Trust Me sees Cath steal her best friend Ally’s CV and medical certificates while drunk at a party. Discarded by Ally who has quit her job to emigrate to new Zealand to live a life of leisure on a farm, Cath assumes her identity and instructs her daughter to call her by her new name.

Moving to Edinburgh, Cath enrols at a hospital as a senior doctor. Ally’s years of experience cause the interviewer to question why she’d want to take a role at such a small and struggling hospital. But Cath doesn’t falter, and joins the fast-pace of A&E, with the help of a pocket-sized Grey’s Anatomy.

Re-setting bones and draining blood, Cath successfully wings her way through her first few days, but it’s only a matter of time before her double-life catches up with her. It’s an absolutely insane and unlikely concoction that makes it the perfect psychological thriller.

We are all more than familiar with that feeling when a television drama centers around our expert area, and we are driven to frustratingly shout at the screen: ‘that would NEVER HAPPEN at a magazine,’ or ‘lawyers do not bribe juries!’ But, medical specialists watching Trust Me will be hard-pressed to unpick it.

Scriptwriter Dan Sefton actually spent most of his life as an A&E medic. The programme draws on his real-life experience, which he’s previously applied to the likes of writing credits on Holby City, Casualty and Doctors. It shows the immense pressure on the NHS and the emotional struggles staff have to overcome after a day’s work.

And to ensure maximum accuracy, the cast spent a few days training as doctors and learning the tricks of the trade. Let’s just hope none of them get too carried away…

With such high stakes, the show promises edge-of-your-seat tension.

How will Cath’s true identity be inevitably exposed? Will her daughter slip up? Will her new lover Andy – a consultant at the hospital – discover her secret? Will her ex-husband find her and uncover her past? Or will she drop the ball in hospital, and cause a patient’s death?

With everything to lose, the programme will have you gunning for Cathy to succeed -  and wiping the sweat from your brow at regular intervals.

It might also have you wondering if a copy of Grey’s Anatomy and a little casual signature forgery are actually all it takes to fake it as a doctor. Thankfully the BBC wrote this revealing feature on just that.

If the previous four points haven’t already had you turning to iPlayer, Cath’s ex-husband Karl is played by none other than Blake Harrison of Inbetweeners fame. 

It’s difficult to imagine him being anything other than a dimwit teenager with cringy dance moves and a penchant for the word ‘clunge’ but Harrison pulls off the recovering alcoholic role with panache, as he seeks to regain trust in his relationship with Cathy and their daughter.
