The party celebrating Lainie Lovett’s father-in-law’s birthday gets exciting pretty quickly when one of the guests keels over just as the magnificent golf-themed birthday cake is being served. That he happens to be the most obnoxious guest at the shindig leaves the other guests less than shattered by his sudden passing. But when it’s determined that he didn’t die of natural causes, and a few of the guests, including the guest of honor himself, arouse suspicion, Lainie’s in-laws ask her to step in and clear her father-in-law’s name. Meanwhile, Lainie’s daughter Karen, who has fallen madly in love with one of the waiters also under suspicion, needs Lainie to exonerate him, as well. In honor of her husband’s memory, her daughter’s love life, and that spectacular birthday cake, with its chocolate golf balls and candy clubs, Lainie must figure out who murdered the party guest—while trying to avoid getting clubbed, herself.
