Thomas, en el otoño de su existencia, vive solo y aislado en su piso en un sótano, y con una radio, un tablero de ajedrez y una foto de su esposa como única compañía. No se suele aventurar a salir a la calle porque cuando lo hace el mundo exterior le recuerda lo mayor que es, lo solo que está y le vienen a la mente tiempos pasados. Se siente en una historia sin final, y además se tiene que enfrentar a su pasado. “Soy mayor y la vida es larga”. Ópera prima de Miika Soini, "Thomas" es una película sobre la compasión, la clemencia y la expiación.
Middle-aged municipal architect Mikko is frustrated with his job and his marriage, so for years he has directed his energy into renovating a turn-of-the-century wooden villa on the seaside. One beautiful summer evening Mikko and his wife Liisa invite old friends to a party in the villa: divorced intellectual Erik who gets along a little too well with Liisa; and noisy building contractor Hessu with his young and sexy new wife Pirre. Their increasingly drunken discussions are interrupted by a surprise visit from Mikko's and Liisa's daughter Jonna and her husband Pete. A conflict between the father and the daughter ensues in front of the guests.
