Eighteen-year old Ashley's life is headed in the wrong direction. She's been hanging out with a bad crowd and seeking an escape from the drama at home. Everything begins to change when a handyman working on the family's house encourages her to volunteer for a Christmas play with underprivileged children. Ashley finds purpose by helping people in need and uses that to help heal her troubled family. Together, they discover the impact one person can make through the gift of giving.

Based on the Pretty Little Liars series of young adult novels by Sara Shepard, the series follows the lives of four girls — Spencer, Hanna, Aria, and Emily — whose clique falls apart after the disappearance of their queen bee, Alison. One year later, they begin receiving messages from someone using the name "A" who threatens to expose their secrets — including long-hidden ones they thought only Alison knew.
