Summer with Cimorelli

The episode begins in the Cimorelli's house in complete disaster mode. As the girls sit on the couch and explain to a pair of police officers exactly what happened, we flash back to Christina convincing her parents to let her be in charge of her sisters while they go off for the summer. As soon as the parents are gone, the girls throw a backyard BBQ/party behind Christina's back. The police officers explain that the neighbor has agreed not to press charges if the girls will pay for his car. Relieved, the girls excitedly agree until they realize that they only have six dollars left to last them all summer. What are they going to do?
