The Franciscan monastery looses its guardian (superior). However it will receive an ancient cathedral treasure back, a crucifix luted by the Russians in Word War II. An Orthodox archbishop will deliver it to a delegation father Laurentius is to lead diplomatically with his Catholic archbishop. Alas, his previously unknown exact lookalike Schmitz and his partner Paula kidnap Laurentius, so he can pose as him to steal the crucifix. Simpleton friar Sebastian first smells a rat when the fake Laurentius is less helpful to hide the old, stinking dog Anka.
