Okay, what the heck is this TV series?

I watched a season opener of a series a few weeks ago, and it seemed promising, but I can’t remember the name of it or whether it’s a new series or one I saw on Netflix or Amazon.

The premise is, I think, drug intervention. A couple of FBI types are assigned to a drug interdiction team at the border, and the first episode has them going into Mexico. On the way back to the US, they end up in a firefight with the agents. It’s not Narcos.

Any ideas?

NCIS:LA had an ep like that not too long ago.

There’s a scene in the recent film Sicario like that.

Ah hell, that’s it. No wonder I couldn’t find a series. My brain is failing.
