Patrollers carry out a suspiciously lengthy strip-search on a smuggler, dispose of some controlled explosives with a controlled explosion, and suffer some contentious fallout from a visit to a Mexican restaurant. Meanwhile, the 'virtual border' gets a real grilling from a BBC reporter. Comic mockumentary following the SBP, the visible presence ensuring the border remains invisible.

The SBP are alert and ready to deal with any border situation, be that deciding if an abandoned fish is a Free State fish or property of the Queen, the Continuity Nine County Sovereignty Committee striving to unify the nine counties of Ulster or simply tracking animals by their accents. Cross-border crease-ups featuring the men and women working hard in a soft terrain.

Does a plank across a stream constitute an illegal border crossing? Is chorizo still legal in Northern Ireland? Thankfully the SBP are here to provide information and clarification.
