Pick of the Day

Big Life Fix, 9.35pm, RTÉ One

Like the BBC series of the same name, a group of leading designers, engineers, computer programmers and technology experts are set the task of creating inventions that will transform people's lives.

In the first episode, the team will try to provide a better quality of life for 68-year-old grandmother, Jacinta Dixon, whose world has been torn apart by a rare form of Alzheimer’s.

This fix is led by designer and innovator Lorna Ross who, during her 30-year career, has worked for some of the world’s biggest organisations, from the US Military to the prestigious Mayo Clinic.

The Guards: Inside the K, 9.00pm, Virgin Media One

With extraordinary footage, this brand new documentary series offers viewers unprecedented access to the garda of The K, Ireland’s busiest policing district which includes Blanchardstown, Finglas and Cabra.

Each episode highlights issues ranging from gangland violence to the drugs epidemic sweeping the country. This is pretty hardcore viewing.

In episode one, with gang violence at an all-time high, the guards in the K battle to keep guns off the streets and to reassure the community.

Zoey's Extraordinary Playlist, 10.00pm, E4

Jane Levy – who you might remember from the US sitcom Suburgatory - stars here as Zoey Clarke, an introverted computer programmer living in San Francisco.

She also pops up in Castle Rock (see below).

An earthquake occurs while she is getting an MRI scan, which causes the MRI technologist's massive music playlist to become implanted in her brain.

Not only that, she soon discovers that her mind can now perceive the innermost thoughts of other people in the form of popular songs.

Sounds daft, so it's got to be worth a look. Besides, Lauren Graham's in it, too.
