Make no mistake: Nazi hunting is a stressful job.

It's all about the high stakes and high emotion in "The Debt" trailer, the upcoming espionage thriller about Mossad secret agents -- played by Jessica Chastain, Sam Worthington and Marton Csokas -- who track down and supposedly kill a notorious Nazi war criminal in 1966 East Berlin.

Cut to 1997 and the retired agents -- now all grown up as Helen Mirren, Ciaran Hinds and Tom Wilkinson-- discover they maybe didn't get the job done after all when someone starts claiming to be the man they killed.

While the younger and older versions of the three main characters look absolutely nothing alike, "The Debt" appears to be the kind of taut and exciting thriller that's going to be just the ticket in closing out the summer. Check out the trailer below and prepare to witness the entire mission when "The Debt" hits theaters on Aug. 31.
