The film "Park" (Lee Jung-Jae) and "Kim" (Jung Woo-sung) lead competing divisions within South Korea's intelligence agency when an assassination attempt targets the President during a visit to Washington DC. This leader, who seized power through a coup in the 1980s, has many adversaries. As events unfold, it becomes clear that there’s significant urgency to determine how those attempting the attack obtained such detailed knowledge of the President's schedule. The possibility arises of a mole – someone known as "Donglim" – who may have become embedded within their agency. Soon, an atmosphere of suspicion and intense rivalry leads Park and Kim into conflict as they race to identify the spy and protect their positions, resorting to increasingly questionable and brutal tactics before a planned meeting in Bangkok. As frequently happens when an actor takes on directing duties, the film suffers from a lack of impartial perspective. The narrative falters at several points during the investigations; I struggled to keep track of who was acting against whom, what alliances were in place, and the story felt slow moving at times. There’s a lot of talking, but it doesn't help develop the characters into individuals we can connect with. A few unnecessary side stories also muddy the waters, failing to offer much value until very late in the film. The conclusion features a twist that is interesting, but ultimately feels forced and unbelievable; I left feeling disappointed.
