Connor's first official mission - help Gisela blend in at school - goes terribly wrong when it arouses Tanya's suspicion about the Heath's "house guest." The good news is that Tanya thinks Gisela is a South American pop star. The bad news is that she wants Gisela to sing at her benefit concert... and Gisela can't carry a tune in a bucket - not even if it's duct-taped to it. Neither Connor nor Gisela have any ideas how Gisela can avoid expose - or worse: total public humiliation. Who would have thought the answer would end up coming from Ty, whose been scheming to get Gisela-obsessed Lily in trouble.
