5 - 18: Hazardous to Your Health

Dylan and Valerie fly to Punta Brava, Mexico where they team up with Dylan's PI, J. Jay Jones, where they hope to plan and execute a complex caper to rescue Erica and reclaim Dylan's inheritance from Kevin and Suzanne who are hiding out down there. Jonesy and Valerie impersonate a tourist criminal couple on vacation where they pretend to run into Kevin and Suzanne (who are living there under their new aliases of Karl and Kitty Cavendish), in order to get the password for Kevin's offshore bank account where he is laundering Dylan's $7.7 million. However, Jonesy's plans starts to unravel when Dylan wants to rescue Erica from Kevin and Suzanne, which Jonesy does not want to be a part of. Back in California, Kelly becomes more deeply involved with Professor Finley's organization, leading to a rift in her relationship with Brandon who begins to distrust the egotistical professor.
