Looking for a movie title on ZDF?

I'm looking for a movie title. The film was shown, presumably this year, on ZDF's Monday Cinema, which airs regularly on Monday evenings. The film only came out in theaters a few years ago.

It's about two police officers working on the US-Mexico border trying to catch American drug dealers in Mexico. None of them can be trusted; any of them could be an undercover agent.

The film is an action/comedy. It features many funny lines.

Maybe someone can help me.
