Plot: In 1970, 4 friends – Samantha (Hoffman), Roberta (Ricci), Chrissy (Ashleigh Aston Moore) and Teeny (Birch) – spend their summer off from school saving up money to buy a tree house, in order to make themselves more independent. During this summer of bonding, they make a pact: Whenever one of them needs the others, they will be there. Now, Chrissy (Wilson) is having a baby, and wants Samantha (Demi Moore), Roberta (O’Donnell) and Teeny (Griffith) to share in this life experience with her.
