The adaptation of author Laura Lippman's crime novel centres on two teenagers, Ronnie and Alice (Fanning and Australian actress Danielle Macdonald), who were sentenced with jail time for kidnapping a child when they were younger, reported Ace Showbiz.
Shortly after their release from prison, another kidnapping takes place in their town, leaving the newly-freed Ronnie and Alice under suspicion once again.
Banks has been cast as the detective investigating the new kidnapping case, while Lane portrays Ronnie's over-protective mother.
"Every Secret Thing" opens on May 15 in the US and July 22 in the UK.
