The Samurai and the Prisoner

The Samurai and the Prisoner (2026) is a Japanese mystery-drama you can watch online on iFILM, set during a castle siege in 16th-century Japan. It's the first jidaigeki from Kiyoshi Kurosawa, the director behind Cure and Pulse.

Lord Murashige rebels against the tyrant Oda and ends up trapped inside his own castle as enemy troops close in. Then people start dying inside the walls, one after another, with no clear culprit. Somewhere among his own vassals hides a traitor. His only real chance is Kanbei, a sharp strategist Murashige himself keeps locked in the dungeon — the two form an uneasy truce to catch a killer before the siege finishes them both.

The setup draws on real Sengoku-era history, when revolts against Oda Nobunaga routinely ended in months-long sieges and captured advisors sat in dungeons rather than facing execution. Kurosawa paces this one like a chamber piece — 147 minutes with almost no swordplay, tension building with each new death instead. It's built for viewers who want their samurai story to run on wits, not blades. Catch it now on iFILM with subtitles.
