A new restaurant is opening up in Greenfield, and the Aldens are first in line to help the owner start up a food pantry. They do everything they can to collect donations, from putting up signs to offering a free Thanksgiving dinner for the whole town, but someone keeps moving the signs and even steals the giant turkey that was meant for the dinner. The clock is ticking to get it back, but never fear, the Boxcar Children are on the case.
