It stars Kate Hudson, John Corbett, Joan Cusack, Hayden Panettiere, siblings Spencer and Abigail Breslin, and Helen Mirren.

Jenny and Lindsay are responsible stay-at-home mothers while Helen, an executive assistant to the CEO of one of Manhattan's most prestigious modeling agencies, enjoys a lavish, carefree lifestyle.

One morning, Helen receives a call from Jenny who tells her Lindsay and her husband Paul have died in a car accident, leaving behind their three children, 15-year-old Audrey, 10-year-old Henry, and 5-year-old Sarah.

Things later start to improve for Helen after she begins dating Dan Parker, the children's school principal and pastor, who helps her bond with them.

When she disappears after prom, Helen is forced to call Jenny for backup, too scared to take control of the situation on her own in fear that Audrey will hate her if confronted.

Finally having accepted Helen can cope, Jenny returns the children to her the following morning, and they happily begin to settle into their new family life.
