Two Doors Down focuses on neighbours living side by side in a typical Glasgow suburb. BBC Scotland describes the characters as "not so happily living together" - the neighbours are constantly visiting uninvited, and overstaying their welcome, at Beth and Eric Baird's house. Beth is often taken advantage of by her neighbours, frequently having to make tea, pour drinks and prepare food, while the remaining characters chat in the living room. Eric and Beth therefore try and avoid their neighbours as much as possible so they can enjoy some peace and quiet in their own home.
