♪ Oh, christmas tree oh, christmas tree ♪ the christmas tree, it's one of the most classic symbols of the season, and for many of us finding that special tree is often a family tradition. The grander the tree, the better. This little green one here, seems to need a home. We all remember that puny little tree in the charles schultz classic, a charlie brown christmas. Can't you tell a good tree from a poor tree? What kind of a tree is that? What a tree! If only charlie brown could see this, the christmas trees at this farms in new jersey. Families have been finding the perfect tree here for 100 years. It's exciting. We're getting a tree! Our family the actors is sandy, a struggling single mother who is injured and out of work, and her two kids, joseph and isabelle. Mom, look! We want this tree! That one is nice. Times are tough for this family. We can't afford this one. I'm sorry. We can't go over $25. The kids' dreams are dashed as they find out they can only afford the straggly tree. Look at this one. It's too small. It's too small, mom. And it doesn't have that many branches. But their mother can only afford the charlie brown tree. What would you do? Guys, we cannot afford those trees. We have a budget. Honey, please don't cry. I've always dreamed of a tree like that. Mom, can we get this? Joseph, we cannot buy such a big tree. Are you guys getting a big tree? I hope so. What did I tell you the budget was? I want to get it. Immediately this woman and her son are drawn to our family and they move in a bit closer. Did you get your tree?

They think they need a tree big enough for santa to come. I know. I can't even talk about it. The family walks away but chris seems concerned. She can't keep her eyes off her family. And then -- she's talking to her husband. Why don't you find out which one they like. She's telling her husband let's do it, let's do it. Excuse me, where is the tree that you had? I think he put it down over here. I'd be very happy -- you don't have to. I'd love to. It's too much money. Why would you do that? Because it's the holidays. Is this the one you guys liked? It's beautiful and I think it will look beautiful in your house. But you have to be extra special to santa and your mom, right? Are they going to get the tree? I am. The tree is $55. A beautiful tree now being wrapped up for our family. But before they leave, this dad has a special request. You have to promise me something, okay? Okay.
