At her best friend Grace's wedding, Ivy slaps her three times because the bride is carrying a real bouquet. It turns out the real Grace is severely allergic to real flowers and would never choose a real bouquet. The three slaps and a coded message uncover a shocking impersonation scheme: the fake bride is actually Grace's long-lost sister, Tiffany, who murdered Grace out of jealousy, underwent plastic surgery to impersonate her, and faked a pregnancy to force her into marriage. Truth and justice arrive belatedly amidst bloodshed and lies.
