How to watch Line of Duty in order

Last updated: August 6 2026

Written by: ChronoChris

Line of Duty is the twist-heavy British police thriller focused on anti-corruption unit AC-12 and the famous question of who is bent. Whether you want a quick binge or a full franchise marathon, having the right watch order makes the experience much smoother. Even when the order looks simple, it helps to know where a prequel, revival, or especially important later season changes the best starting point.

Line of Duty mixes case-of-the-season structure with a long-running conspiracy, making it one of the most compulsive modern crime dramas to binge. Knowing the structure ahead of time helps you decide whether to commit to the full run or begin with the era that best matches your taste.

πŸ• Release Order

Release order is critical because each series adds new layers to the corruption plot and builds on major reveals from earlier years.

  1. Line of Duty Series 1 (2012)
  2. Line of Duty Series 2 (2014)
  3. Line of Duty Series 3 (2016)
  4. Line of Duty Series 4 (2017)
  5. Line of Duty Series 5 (2019)
  6. Line of Duty Series 6 (2021)

Although new guest leads arrive often, this is not an anthology. The AC-12 storyline keeps threading everything together.

πŸ“– Story Chronology

Chronology and release order are the same. The six series unfold in sequence and steadily deepen the institutional conspiracy at the center of the show.

  1. Line of Duty Series 1 (2012)
  2. Line of Duty Series 2 (2014)
  3. Line of Duty Series 3 (2016)
  4. Line of Duty Series 4 (2017)
  5. Line of Duty Series 5 (2019)
  6. Line of Duty Series 6 (2021)

Which Order Should You Choose?

Watch Line of Duty in release order and resist the temptation to jump straight to the most famous later twists. The fun comes from watching suspicion accumulate around every witness statement, every transfer, and every hidden alliance. If you enjoy procedural precision with serialized payoff, starting at series 1 is the only way to get the full impact of AC-12's investigation. If the first few episodes click, staying in order gives you the clearest emotional through-line and avoids spoiling the character growth that later chapters depend on.
