Winter 1993 in the suburbs of Belgrade. Marijana throws a Ninja Turtles-themed costume party for her daughter´s 8th birthday, with family and parents attending. This celebration is an opportunity for everyone to let off steam in a context of war and crisis. Cleverly written and delightfully acted, Celts is an incisive, mischievous social dramedy, which uses a light touch for some sensitive issues, and it does so with charm.
