In a teaser, we see Sam (on a WOOHP speedboat) arrive near an island where a construction project is in process. She tries to make landfall, but can't penetrate an invisible forcefield. She declares that she'll "need to find another way inside." Meanwhile, Clover and Alex walk across campus wondering what's up with Sam and decide that spying on her is the only way to figure it out! Meanwhile, meanwhile, at WOOHP, Sam takes a picture of herself in full mime get-up. She writes a note on the photo and mails it to Jazz Handz, telling the villain she'd like to meet him. Back at the penthouse, Alex and Clover find Sam's envelope from the previous episode and immediately grow suspicious of her secret activities. Just then, Sam comes home and sees them. Realizing she needs to throw them off her trail, she has Jerry WOOHP them and send them on a bogus mission (to check out a villain that's terrorizing a local playground). Then Sam's phone rings. It's Jazz Handz. He agrees to meet her. When Clover and Alex reach the playground, they find nothing more than a funny kid bully. They decide to find Sam. To their utter shock, they find her meeting with Jazz Handz! Next, Clover and Alex follow Sam to a covert technology facility¿ where they witness her steal a microchip. Clover and Alex can't believe it! As Sam leaves the facility, they intercept her and tell her they're taking her in to WOOHP for her own good. But Sam isn't about to give up without a fight. After a big action sequence, Clover and Alex capture Sam and take her back to WOOHP. That's when Jerry and Sam come clean explaining that Sam was in deep cover, trying to figure out what Jazz Handz's next plan is. Clover and Alex realize they wrongly accused Sam and apologize. Sam apologizes too. They all agree to all work together to bring down the baddie. In a b-story, Mandy and Mindy move in to the girls' penthouse when a pipe in their dorm room breaks.
