Summary for the movie
Marcel De Lange is a struggling sculptor whose work and sanity are derided by the New York art critics. After waspishly officious critic F. Holmes Harmon ruins a sale for De Lange by dismissing his expressionistic cubist work as "tripe" and later gloating about it in his column, the distraught artist goes to the river to drown himself. There he discovers the half-drowned body of the notorious serial killer, the Creeper, and takes him back to his studio to recover. Feeling empowered by the friendship of the acromegalic sociopath, De Lange tasks him with murdering the critics who have pilloried him in print. When successful commercial artist Steve Morrow is wrongly suspected of the crimes, his art critic girlfriend Joan Medford decides to follow her instinct about a mysterious bust De Lange has suspiciously covered in his studio, and she decides to snoop around.
