What to do when nine pounds of radioactive isotope are missing? Call Mark Wahlberg, of course.

“I’m totally calm,” says Wahlberg’s CIA operative James Silva in this new trailer for the upcoming Mile 22.

“That’s because you’re mentally unstable,” snipes colleague Alice (played by Lauren Cohan).

The STX Entertainment action thriller, directed by Peter Berg from Lea Carpenter’s screenplay (story by Graham Roland and Carpenter), follows Silva, a CIA operative who’s aided by a top-secret tactical command team and must retrieve and transport an “asset” who holds life-threatening information.

Also starring are Iko Uwais, Ronda Rousey and John Malkovich. Producers are Peter Berg, Mark Wahlberg, and Stephen Levinson.

Take a look at the trailer above. STX releases Mile 22 on August 3.
