A gentleman's sleep is interrupted by a giant bedbug (?), resulting in a comic battle. Unusual for the auteur, there is no 'trick photography', just an early mechanical effect featuring an over-sized insect. There's not much to the film beyond a brief laugh and its historical place in the canon (as an antecedent to 'Them' (1954) etc.). Remade by Méliès as 'Un Bon Lit' in 1900.
