ITV advert - argh what violin music?

[Scam]

I just saw an advertisement for ITV drama where Endeavour Morse is talking to camera whilst having a gunfight in a forest.

It's got a really recognisable piece of classical music in the background, sounds like a single violin perhaps. What the heck is it?

Edit: Found it on YT: https://youtu.be/2rwlG-myLRs

Ahh- thank you! It was from Arrival that I recognised it. Gosh, really hits me in the feels that piece...
