Decoded

Decoded (解密, 2024) is a large-scale Chinese thriller you can watch online on iFILM. Director Chen Sicheng adapts Mai Jia's novel about a man whose gift for numbers becomes both his rescue and his ruin.

The 1940s, a world at war, when reading the enemy's cipher traffic fast enough decides who lives. Rong Jinzhen sees patterns in numbers that escape everyone around him — he idly cracks a problem the whole class is stuck on, and the wrong people take notice. Pulled into the secret Unit 701, he is set against an enemy supercode called Purple, a duel fought not on any front but inside his own mind, where waking life bleeds into dreams.

Liu Haoran carries the lead, with John Cusack beside him in an international cast. At 156 minutes the film goes big — pre-war Shanghai, mazes of code, and the price a prodigy pays for every line he unravels. It's for viewers who like their espionage built on intellect rather than gunfire. Stream Decoded online on iFILM.
