Forty-year-old Lina's father had always advised to "never trust a skinny chef", yet she learns at his funeral that she must battle her underweight, food truck owning, new stepmother, or risk losing her childhood home, along with treasures that only Lina knows hide behind those walls. When Lina's sanity derails before her best friend Ricky's eyes, he labels this chapter of their lives, "The Great Snap", as she battles more demons than just her step-mother and adulterous husband, while raising young twins and readjusting to life in suburban Detroit, after twenty years away. Feeling powerless, the curvy blonde shamelessly succumbs to her lust for life with multiple men and youthful indulgences, while rekindling old flames and casting vengeance upon previous offenders. Determined to take back what is hers, she realizes her admirers can be useful. The Motown Mood Cafe, owned by Lina's lesbian mother figures, serenades the story through time, as the same town residents are followed through the past, and connected in the future. The circle of mid-life swirls through generations at the mystical age of forty, and the two devoted friends look for courage, in search of their next 'great'.
