Truth Makes Free(2020)

A Security Service Major wishes to "buy" gullible priest Zieja and turn him into an agent who will discredit the opposition. The priest's interrogations become a natural pretext for a journey through the history of Poland in the twentieth century: from the Bolshevik war of 1920, through World War II, up to modern times. It turns out that the seemingly naive Father Zieja is actually a clever rebel.
