In some of the world's greatest fishing destinations Robson Green challenges local masters of their craft over five rounds of competitive fishing. To win he has to catch the most, the biggest and the best - it is Robson versus the world.

Mexico has coastline on both the Pacific and the Caribbean, offering a wealth of different salt water targets. The first stop for Robson is the marlin capital of the Pacific, Cabo San Lucas. There, the plucky Geordie faces a match-up with a trophy-winning marlin hunter in a battle to catch the most of these iconic game fish.
