Stacey has left the Babysitters Club and becomes friends with a group of girls. However, when the group attends a famous concert, the girls begin to do bad things, causing Stacey to get in trouble and appreciate her friends. Before the concert, the girls were using Stacey's employee discount at a store in the mall to buy things than returning them for full price. At the concert, the girls bring in wine but get caught. They pretty much blame it on Stacey but luckily she had diabetes (yes, luckily) and she wasn't getting sick, so she couldn't have drunk the wine (which has sugar in it) Afterwards, she has no friends and decides to return to the BSC, and she becomes a member again.
