The film focuses on 10-year-old Anna Beam who lives with a chronic disorder, but is miraculously cured after she lives through an accident. As a mother of three, herself, Garner, 43, was touched by the movie.
“I think for most of us, it’s playing pretend, but it’s a pretty real story,” she told PEOPLE. “I don’t think you have to dig very deep when there’s a child. The great thing for us at the end of the day is we can shake it off and go home and be surrounded by health, and that perspective was a real gift to the movie.”
Garner stars alongside Kylie Rogers who formerly appeared in ABC’s The Whispers, and Martin Henderson who plays Garner’s husband, Kevin Beam.
