The critically acclaimed zombie thriller 'Train to Busan' now has a sequel. And it looks as horrifying as its predecessor. For one thing, these guys are not practising social distancing.

The teaser trailer for 'Train to Busan Presents: Peninsula' has arrived, if your nerves can stand watching it.

The official plot synopsis reads: "Four years after South Korea’s total decimation in 'Train to Busan', Jung-seok (Gang Dong-won), a soldier who previously escaped the diseased wasteland, relives the horror when assigned to a covert operation with two simple objectives: retrieve and survive.

"When his team unexpectedly stumbles upon survivors, their lives will depend on whether the best—or worst—of human nature prevails in the direst of circumstances."

Actress Lee Jung-hyun plays one of the survivors, alongside child actress Lee Re.

Director Sang-ho Yeon is back from the first film.

The film was originally set to hit cinemas this summer but is now waiting for a new release date.
