“Deception is an art. Truth is a test. Is love a lie?”

So reads the pithy text in the latest promo for Allied, Brad Pitt and Marion Cotillard’s World War II spy drama. Perhaps one of the most unsettling things you can learn about relationships is that there’s no way to know for sure whether the people close to you love you as much as you love them. (And, man, after that Brangelina split, is love even real anymore?) Pitt and Cotillard take this fear to the extreme in their upcoming movie, spinning a tale about two spies whose work takes a serious toll on their personal relationship.

The promo gives us a few more looks at what’s in store: card tricks, old cars, meaningful stares, meaningful stairs. Our heroes Max and Marianne have formed a relationship with each other despite the pressures of the war, even going to far as to have a child together, but as soon as they get to London to start making a home it all comes crashing down. When you’re both spies for a living, can you really trust each other behind closed doors?

Here’s Allied’s official synopsis:

Allied is the story of intelligence officer Max Vatan (Pitt), who in 1942 North Africa encounters French Resistance fighter Marianne Beausejour (Cotillard) on a deadly mission behind enemy lines. Reunited in London, their relationship is threatened by the extreme pressures of the war.

Allied is directed by Robert Zemeckis and opens in theaters November 23.
