LOOK BACK AT KEIRA KNIGHTLEY'S STYLE HIGHS & LOWS HERE
The pretty pair star alongside two equally attractive actors - namely, Sam Worthington and Guillaume Canet - in the film about love and betrayal.
Keira and Sam play the role of seemingly perfect couple Joanna and Michael, who's relationship is put to the ultimate test in the space of just one night.
While Michael is attempting to resist temptation on a work trip with his sizzling colleague - played by Eva Mendes - Joanna is left at home, where she encounters an old flame - the gorgeous Guillaume Canet.
Naturally, the trailer doesn't give away the ending - so whether both sides choose to stay faithful remains to be seen...
