What to expect from Nine Bodies in a Mexican Morgue

Billed as a "strikingly original and taut" drama with a "jaw-dropping" twist, the story begins when a light aircraft carrying a small group of passengers crashes in the Mexican jungle.

"As the story unfolds in flashback, we meet the survivors as they fight against the heat, a shortage of supplies, the many dangers of the jungle – and each other. 

"The setting becomes increasingly tense and claustrophobic until finally the identity of the killer and the truth are revealed."

What have critics said about Nine Bodies in a Mexican Morgue?

Following its BBC debut on 26 September, critics were quick to praise the six-part thriller. 

In its five-star review, The Guardian wrote: "I don't know that anything has given me greater or purer joy this year. Nine Bodies in a Mexican Morgue is unabashed nonsense, without a trace of cynicism or guile in a world stuffed to bursting with both. I offer my undying allegiance to its Agatha Christie-meets-Lost shenanigans."

Meanwhile, Decider penned: "In Nine Bodies, it's the suspicion and what's left unsaid among its plane crash survivors that has us hanging with them in their jungle clearing," while Globe and Mail added: "Bestselling suspense author Anthony Horowitz is behind the show – and while his dialogue can sound a bit flat, his mystery craft mostly makes up for it. I'm hooked after two episodes."

Nine Bodies in a Mexican Morgue is available to watch on BBC One and iPlayer now.
