Comedy starring Tina Fey as Kate Holbrook, a successful single businesswoman who realises in her late 30s that, owing to an unforeseen gynaecological problem, she has left it too late to have a baby. Undaunted, Kate approaches a surrogacy agency run by the formidable Chaffee Bicknell (Sigourney Weaver), and engages working class girl Angie Ostrowiski (Amy Poehler) to be a surrogate mother. Once she finds out that Angie has become pregnant, Kate throws herself into reading childcare manuals, researching good schools and installing baby equipment in her apartment in between her business engagements - but the course of motherhood never did run smooth and Kate soon finds herself in circumstances way beyond her control.
