Directed by Edvin Laine and Viktor Tregubovich, Trust (1976) is a Finnish-Soviet historical drama film that follows the relations between Finland and the Soviet Union. In December 1917, the Finnish delegation, composed of Chairman of the Senate Finance Department P.E. Svinhufvud (Vilho Siivola), Senator Carl Enckell (Yrjö Tähtelä) and State Secretary Gustaf Idman (Yrjö Paulo) arrive in St. Petersburg to meet V.I. Lenin (Kirill Lavrov) to gain recognition for the country's independence.

Office clerk Eero Koskinen prefers to spend his nights drinking and reminiscing the war with his friends, instead of taking care of his wife and two children. A two-week drinking spree gets him fired, and a new job is not easy to find because of his reputation. He goes to a rehab centre in the countryside for a couple of weeks, but with no permanent result. Meanwhile, his wife has to get a job and is employed by her old sweetheart, now a recently divorced successful businessman.
