Over two years, the Big Cats team mounted filming expeditions across the globe.

All cats are elusive and shy creatures, and notoriously hard to film.

None more so than snow leopards.

The Big Cats team set out to film a lonely male leopard's search for a mate.

After months of planning, director Anna and cameraman Hector embark on a five-day journey high into the Indian Himalayas… the home of the snow leopard.

We're on our way up to the mountains, it's starting to get a little bit windy and a little bit steep, and it's going to get a bit more hairy from here on in.

In winter, there's only one road in.

At 4,000 metres, they're still climbing.

This is the bit I've been dreading.
