In the center of the plot is Ivan Lutoshin, a neurologist by profession and a loser in life. He finds out that he has an inoperable brain tumor and he has six months to live. He decides to commit suicide: after getting drunk, he goes out on the expressway and stands on the lane. But the car manages to pull out of the road. Police operative Tumanov is driving: after learning about the problem of a random acquaintance, he offers him to participate in deadly operations to catch bandits - if they kill him, then at least not in vain.
