A satirical sitcom set in Northern Ireland that follows two neighbouring families — one staunchly republican and one fervently loyalist — whose children have married one another, much to the horror of both sides. The comedy mines the absurdities and contradictions of sectarian politics in the region, with the feuding in-laws constantly clashing over flags, culture, and tribal loyalties. Despite their mutual contempt, the characters repeatedly find themselves thrown together by circumstance, exposing the ridiculousness of their entrenched positions.
