OF UNKNOWN ORIGIN

Everything can change for Bart: a young driven director very much appreciated by his boss, will soon get a promotion with a big responsibility: he will first have to bring in a national reorganisation project (in the USA) for his firm.
Everything seems to go well. His wife and sun are on a holiday, so he will have to complete this task on his own. But he didn’t expect an invisible, resistant and very quick intruder to enter his home.
It will be a thrilling duel and his nice and cosy interior quickly changes into a dangerous jungle that holds unpredictable traps.
