13 Going on 30 follows the tale of Jenna Rink (Jennifer Garner), a 13-year-old girl who wishes to be “thirty, flirty, and thriving” and wakes up to find her wish has come true — only she barely recognizes the conniving, manipulative adult version of herself. With a sprinkle of youthful exuberance, she goes about righting her adult wrongs and reconnecting with former best friend, Matt (Mark Ruffalo).
