Sam (Rebel Wilson) is a world-class secret agent… and a pretty terrible maid of honor. After blowing off bridal duties for an international spy mission, she’s demoted to bridesmaid at her childhood best friend’s wedding. What should’ve been a weekend of reconnecting and celebration turns into a five-star death trap when armed mercenaries crash the big day. Sam’s the only one who can save the bride and hopefully earn back the trust she lost along the way. Dodging bullets and trying not to ruin the floral arrangements, Sam takes on the ultimate wedding crasher, realizing that sometimes the toughest mission isn’t taking down the bad guys, but showing up for the people who matter.
