Rollback

Eighty-seven-year-old Dr. Sarah Halifax, the woman who decoded the first radio transmission from aliens nearly four decades earlier in 2009, is offered a chance to rollback time through an experimental rejuvenation procedure that would allow her to work on the just-received alien reply, but life gets complicated when she and her husband Don agree to the treatment, which works for him but not for her, leaving her with a twenty-five-year-old spouse.
