Operation Zorro has at last arrived. The Good Guys are making final preparations for the trip to Spain where the Operation will take place. Problems immediately arise when they find their luggage is over weight thanks to Beach's trunk, Strings' guitar and the Commissioner's golf clubs, which Mark Kemp (his nephew) is taking to his villa for him.

There are further problems when Beach looks at Ray's nine-year-old passport and notices that the photo shows a younger Ray with more hair. He insists Ray wears a wig to get through Passport control.

At the airport later, Mark leaves his uncle's clubs unattended and they get blown up. Ray and de Sade end up dropping Beach's trunk on his foot. In desperate need of some pain killers, Beach ends up taking de Sade's special forces pain killers only to learn they are very powerful and have weird side effects. He turns over control to Ray just before he starts hallucinating. After a rather disturbed journey thanks to a manic Beach, the Good Guys arrive in Spain and try to make contact with the MI6 agent using their secret password (the lyrics to Summer Holiday) which earns a few funny looks from tourists.

Beach, who has been left in the sun to sweat out the toxins and is feeling better, makes contact with the Agent who turns out to be none other than their old dodgy accountant Roy Leyton who also owns the hotel they're staying in. Upon their arrival, Leyton informs them that their rooms aren't available yet so they are forced to sleep on the sun lounges by the pool.

Ray has meanwhile stuck lucky with a lady but unfortunately things go wrong when she finds out he's wearing a wig. This prompts Strings to write The Baldy Song. Convinced they have a hit on their hands, Hugo Blick their producer decides to make a video choreographed by Mark.
