One warm night four children stood in front of a bakery. No one knew them. No one knew where they had come from. Henry, Jessie, Violet, and Benny used to live alone in a boxcar. Now they have a home with their grandfather, and they have become friends with a famous movie star! While Tate Radison was filming his last movie, a lot of odd things happened. No one knows who was responsible for the canister of film disappearing or for the other problems. Now Tate wants to keep his presence in Greenfield a secret to avoid any more mishaps. But soon a note arrives in his mailbox, and the troubles start again. Why would someone want to ruin Tate's career? It's another mystery for the Boxcar Children!
