The The night before their old friend's wedding, three adventurous bridesmaids face more than they could have imagined. Beautiful Becky (Rebel Wilson) is about to marry handsome Dale (Hayes MacArthur). Bridesmaid Regan (Kirsten Dunst) is a successful businesswoman with secret ambitions since she couldn't get married first. Although Gena (Lizzy Caplan) may seem like a sharp-tongued cynic, she actually has an emotional nature. Katie (Isla Fisher) is a naive, silly woman who likes to live beautifully. Becky wants a quiet bachelorette party but they're not happy about it, so they make their own plans. Their plans come true in an unexpected way... The worst thing is the broken wedding dress... Will this wedding dress survive until the wedding? Will close friends survive tonight? Time passes quickly and an unforgettable weekend begins that will change their lives completely. Again, Leslie Headland has adapted from the hit play The Bachelorette, writing and directing a poignant comedy about ludicrous disappointments, women on the brink of unexpected developments, and close friends.
