A romantically unattached woman, Annie, fears she is losing her BFF, Lillian, when Lillian announces her engagement. To make matters worse, Lillian has become very close to her boss's wife, the rich and sophisticated Helen, who takes over control of all of the wedding plans after Annie's attempts fail miserably. The bridal group includes the promiscuous tomboy Megan, who propositions every man she meets, the new bride Beca, who experiences her first lesbian experience with Lillian' cousin Rita. After Annie discovers Helen is also fucking her pseudo boyfriend, she seeks comfort from the cock of a friendly Irish cop who pulled her over thinking she was drunk.
