Trailblazers: A Rocky Mountain Road Trip
9pm, BBC Two
Sending a comedian, an actor and a Spice Girl in the footsteps of convention-breaking Victorian explorer Isabella Bird might seem a random concept – and it is, but it actually makes for an endearing, inspiring and very funny adventure in this three-parter. Ruby Wax and her two companions, Mel B and Emily Atack, travel through the Rocky Mountains to Longs Peak, while telling the awesome story of the gutsy 42-year-old single woman who did the same journey in 1873 and fell for a one-eyed desperado called Rocky Mountain Jim. Hollie Richardson

Gamechanging secrets are revealed in tonight’s devastating finale, as the Rees family’s saga comes to an end in dramatic (if slightly overblown) fashion.

We Are Not Alone
9pm, Dave
What if alien invasion classic V was set in Lancashire? That, broadly, is the premise of this gag-filled feature-length sci-fi about a loafer (Declan Baxter) strong-armed into doing PR for the conquering Gu’un empire. Amid an impressive ensemble, Joe Thomas stands out as the sweetest (and stupidest) alien. Graeme Virtue

The Holiday Swindler
10.30pm, BBC Three
Most travel agents are clearly wonderful individuals who merely want the best for their sun-starved clients. On the other hand, some, such as the Brazilian travel agent profiled here – who left lots of miserable tourists in their wake – are anything but. Here’s how a “trip of a lifetime” turned out to be nothing of the sort. Ali Catterall
Film choice
The Wife, Monday, 11.15pm, BBC Two
“Bad husbands of cinema” is a category with almost unlimited choice, but it’s nice to home in on one particular wrong-un. Jonathan Pryce’s here is an all-time git; a needy writer with wandering eyes who, after efforts to write a novel end poorly, suddenly becomes a bestseller. Part of what makes Pryce so insufferable is the way that “the wife” – Glenn Close – plays off him, rolling in wave after complicated wave of care and jealousy and loathing for the dismal man she married. Of all the Oscars Close should have won, she should have won this one the most. Stuart Heritage
