It's Mother's Day in sleepy Longley, New York, and this year, catering sisters Bernie and Libby Simmons help a friend--who happens to be an overworked and underappreciated mom--go to extreme lengths to teach her family a lesson. But when a prank turns deadly, the Simmons sisters will have to cook up a plan to clear their pal's name. . .
Bernie's college roommate Ellen Hadley is burning the candle at both ends. She's grown a successful business baking treats for dogs and cats, and she's a dutiful wife and mother who somehow manages to fit all the cooking and cleaning into her busy schedule. But after her children forget her birthday and her husband forgets their anniversary, her expectations for a memorable Mother's Day are understandably modest.
When Bernie jokingly suggests Ellen fake her own kidnapping to set her family straight, she never imagined her friend would actually go through with it. But when Ellen's husband follows her phony ransom note to an out-of-the-way hotel, he finds the police taking her into custody after she discovers a dead body in her room. Ellen swears she doesn't know the victim, but as police investigate her half-baked plans, they turn up more questions than answers.
Bernie can't help but feel guilty for helping her friend concoct a recipe for disaster, so she and her sister Libby enlist the help of Ellen's kids, and together, they must race to find the true culprit--before Mother's Day is postponed indefinitely. . .
