Bride Alex leaves her would-be groom, Dave, at the altar. Her actions present of problem for their close-knit groups of friends - Alex's sister Jane and her buttoned-up husband, Brad; Max, their gay friend who's not a stereotypical gay; and perpetually-single Penny who's always worried about not finding the right guy. They now have to choose between the couple, who were the lynchpin of their social circle. The problems caused by Alex's actions come to a head at Penny's birthday celebrations the week after the wedding-that-never-was. - 2011 Abc Studios
