A Wilhelmina-induced crisis at Mode finds everyone scrambling to re-create an issue on deadline. Desperate times call for desperate measures, as Daniel and Betty try to break wild child cover girl (guest star Eliza Dushku as Cameron Ashlock) out of rehab for a re-shoot, and Alexis tries to charm the printer (guest star David J. Steinberg) into extending their time. Meanwhile, Betty struggles with an unwelcome (and persistent) visitor who hopes to goad her into making good on a promise.
