Back from the Brink

Sunday, RTÉ One, 6.30pm

Derek Mooney continues his journey around Europe to discover how conservationists are working to repair the damage done to the environment and biodiversity by generations of mismanagement.

Comedian PJ Gallagher is known as a gas ticket altogether, but behind the laughs and wisecracks, Gallagher is very candid about the mental health issues he has had to deal with offstage. Gallagher credits St Patrick’s Mental Health Services for saving his life, and in this documentary, he looks at the range of therapies available for maintaining mental wellbeing, including mindfulness and talk therapy, and some unorthodox methods such as psilocybin – the active chemical in magic mushrooms. It’s all done with Gallagher’s trademark wit and humour, but there is a serious intent to dispel the stigma around mental illness to help others who may be struggling with their own mental health.

Imposter: The Man Who Came Back from the Dead

A strange tale of fraud and fakery is unravelled in this four-part documentary about a fugitive who turned up in a Glasgow hospital in a Covid coma. When authorities tried to establish the sick man’s identity, they discovered he was an American named Nicholas Rossi, wanted in Utah on sex offence charges, and under investigation for fraud by the FBI. But when he awoke from his coma, he insisted his name was Arthur Knight and that he was a victim of mistaken identity. Things were further complicated when it was learned that Rossi (real name Nicholas Alahverdian) had apparently died from a terminal illness. Did Alahverdian fake his own death, or was Arthur Knight real?

They’ll be faced with a variety of tough sewing tasks to test their abilities, and in the first episode they’ll have to knock up a denim midi skirt, transform a bog-standard T-shirt into a fab fashion piece, and create a casual day dress to die for. This series features a new presenter, actor and comedian Kiell Smith-Bynoe, standing in for Sara Pascoe, who is on maternity leave.

The Dry

Wednesday, RTÉ One, 9.35pm

It’s episode three of this drily witty comedy series, and Shiv (Róisín Gallagher) is still living at home and trying to stay sober, but the temptations are piling up, not least because of new boyfriend Alex, who has a taste for the finer things in life. In episode three, Shiv’s mum Bernie (Pom Boyd) and dad Tom (Ciarán Hinds) are shocked to find Alex in their kitchen rustling up a wonderful breakfast – how did their daughter manage to bag such a god? And when’s the wedding? Shiv’s sister Caroline, however, is not too sure if her fellah, Shane, is really “the one”, so she’s fired up the flirting apps and gone on a dating spree – with disastrous consequences. Tom is still covering up that he’s lost his job, but Shiv is suspicious and follows him. She’s not ready, though, for what she finds

Murder, They Hope

Thursday, BBC Two, 9pm

Sian Gibson and Johnny Vegas star as sleuthing couple Gemma and Terry – and let’s be clear: they’re no Marple and Poirot. That doesn’t stop them gamely having a go at working out whodunit, and in this double episode to end series two, the couple are planning their wedding reception and have checked into the hotel two days early to make sure all is prepared, when a wedding gift lands at their feet: a dead guest at the hotel. In the second of the double finale, Terry is forced to reconnect with an old friend who’s in a spot of bother, leaving Gemma to do the crime solving on her own. He better hope she doesn’t do a better job of it without him.

Fleishman is in Trouble

Thursday, RTÉ2, 10.30pm

Previously seen on Disney+, this series, based on the novel by Taffy Brodesser-Akner, is well worth a try on terrestrial TV. It’s a sharply observed drama of divorce, parenting and careering, starring Jesse Eisenberg as Manhattan medic Toby Fleishman, whose increasingly fraught relationship with his ambitious wife, Rachel (Claire Danes), ends in inevitable divorce. Toby finds himself back on the singles market and getting lots of swipes on his dating apps, but his gallivanting is curtailed when Rachel suddenly drops off their kids at his place and promptly disappears, forcing Toby to finally face up to what really happened with his marriage.
