Best TV shows on TV tonight

The Pact season 2, 9pm, BBC One

The second season of writer and producer Peter McTighe’s Welsh noir reaches a sombre denouement as the truth behind Christine’s lies is finally laid bare. It’s an intriguing final act that poses some interesting questions, but doesn’t quite deliver on the promise of the series’ early stages.

We can’t help but wonder if six episodes has been a bit of a stretch this time out. However, tonight’s finale sees a great performance from the drama’s lynchpin, Rakie Ayola as Christine, although we were hoping for a little more of Steven Mackintosh, who was criminally underused as her estranged ex, Harry.

The 10 remaining chefs are up against it as the super-tough semi-finals get under way. First, they have to create a special meal inspired by their favourite memories of food. While the five chefs who impress the most then progress to the next stage later in the week, the others have one more chance to win over judges Anna Haugh, Gregg Wallace and Marcus Wareing as they nervously tackle the dreaded Invention Test, in which they use leftovers from the first challenge to produce a sensational dish.

But who will be going home? Continues Thursday and Friday, when the contestants have a go at cooking in a pop-up restaurant for 20 fellow chefs.

Trailblazers, 9 pm, BBC Two

Emily Atack, Melanie Brown and Ruby Wax aren’t companions we’d necessarily think to put together, but the trio make fantastic company in this three-part travelogue. Inspired by Victorian explorer Isabella Bird, who undertook an 800-mile journey through the Rocky Mountains at a time when it was unheard of for women to travel alone, Emily, Mel and Ruby are off to navigate the Rockies for themselves.

Along the way, they try authentic Isabella-esque experiences including cattle wrangling and mountain climbing, and sample local delicacies such as Rocky Mountain oysters (not what you might think) and pickleback – a shot of bourbon with a pickle-juice chaser.

We Are Not Alone, 9 pm, Dave

Hapless council worker Stewart (Declan Baxter) is recruited by aliens to help them conquer the world in this feature-length comedy from the writers of Ghosts and Horrible Histories. Vicki Pepperdine, Mike Wozniak and Joe Thomas play the blue-hued extraterrestrials who land in Clitheroe, Lancashire, and nominate Stewart to help them achieve global popularity.

With star turns from Rob Delaney and Ellie White, this is packed with punchy satire that veers from comedic to poignant as the aliens become baffled by the stupidity of humanity.

Secrets of the Middle Aisle, 8 pm, Channel 4

Denise Van Outen investigates the excitement, jeopardy and FOMO of the supermarket middle aisle, as she unpicks how discount stores Lidl and Aldi get us to part with our cash for a cheap paddling pool or a cut-price waffle-maker. And it’s all pretty scientific, with constantly changing stock to lure us in, as well as the use of something called ‘the scarcity principle’ to make us grab items before they run out. Even the chaos of the middle aisle is a well-thought-out campaign to add an element of surprise.

Meanwhile, Denise reveals her own middle-aisle favourites and pits Lidl’s own-brand drill against a brand leader with surprising results.
