Julia Roberts anchors powerful mother-son relationship in addiction drama ‘Ben is Back’

A lot can happen in 24 hours.

Set during a single 24-hour period on Christmas Eve, “Ben is Back” follows a mother scrambling to deal with the unexpected return of her son from rehab. The teenage Ben (Lucas Hedges) has struggled with opiate addiction ever since getting hooked on painkillers after a snowboarding accident when he was 14. As the film opens, he’s 77 days sober and has managed to get a daylong furlough from his rehab clinic to spend Christmas with his family in Yonkers, New York.
