The story of four college friends who think they have it all figured out at 40, only to see their lives crumble in an instant. A "business Barbie" discovers her "perfect" marriage and career were a sham; a single mother sees her life lose its meaning when her deaf daughter decides to study abroad; the happy wife of a "prince charming" discovers the love of her life is a narcissistic abuser; and a perpetually teenage girl faces a controversial pregnancy as an "older mom." Together, they must pick up the pieces, rebuild their lives, and find happiness in the process.
