I'll be honest

It's about a guy who tries to get home by getting without a ticket or any permission inside a cargo ship, whose crew is very hostile. The guy is discovered and he has to face with a reality in which the ship is a home for the crew and they have to defend it at any cost, even if they'd have to kill any intruder who could put into(my English is not quite good, so you may find some possible mistakes like this) risk his life. See the film, again if you already did.
