In the following trailer for the Korean time travel film "11 AM" everything goes terribly wrong. The film seems to orient itself towards more Western productions, but it also breaks some new ground by recombining elements from a number of genres. Sounds pretty interesting that the story is actually more about the time travel aspect, but the whole thing also takes place in a deep sea facility and apparently also has mystery elements. So it could all be more of a thriller or even a horror film, maybe a bit of a crime thriller, but definitely confusing and definitely a bit scary...
In the not-so distant future, researchers at a deep-sea laboratory have finally succeeded in inventing a time machine. Heavily burdened by financial stress, head researcher Woo-seok is promised more funding from a mega-corporation, if he successfully completes a test flight. Ji-wan tries to stop his colleague and lover, Young-eun from going on the dangerous flight, but Woo-seok and Young-eun carry out the mission and travel to 11 AM - the next day. They arrive at the planned time only to find the base on the verge of collapse. What could have happened in the 24 hours?
