A young pastry cook is taking a cream cake to a customer, but on the way he places his basket on a seat to have a game of marbles with a telegraph boy. A chimney-sweep then comes and joins in the game. The telegraph boy having lost all, gives up the game, leaving his two partners, who are not long in starting a quarrel. In the meantime a policeman, who has been looking on, joins in the discussion, The little pastry cook who has not been having a good time, does not know how to defend himself, but suddenly an idea comes to him. He picks up the cake filled with cream and decides to crush it on the head of the sweep; but the latter, who has seen what was going to happen, stoops down, with the result that the policeman gets it full in the face.
