New Release

To control the population explosion that nearly crippled the city, New York has instituted Kill Train, a randomized, extermination program where designated subway trains are picked at random, and all the passengers are slaughtered by the end of the line. In this not-so-distant future, we meet Vanessa, a struggling single mom in the midst of a nervous breakdown, who discovers that she, herself, is on a Kill Train. Now, for once in her life and with everything to prove, Vanessa decides she's not going down without a fight.  (learn more)

"The Purge meets The Taking of Pelham 1, 2, 3 if it was put in a blender and Stephen King drank it. Kill Train is scary, funny, grounded, and one hundred percent NEW YORK.”

- Adam Glass (Writer/Producer) Suicide Squad, Teen Titans, The Equalizer, Supernatural

Praise & Reviews

“Kill Train is a breakneck ride on the bus from Speed with passengers from The Purge and no brakes!" 

- Steven de Souza (Writer/Producer) Die Hard, Commando, 48 Hours, and Sheena Queen of the Jungle

This morbid lottery in Kill Train means any subway could become a death trap, creating an atmosphere thick with suspense and brutality right from the very first page. Cuartero-Briggs crafts a story that is unique and makes us question how far society might go when pushed to its limits.
