Repeteix una mica el plantejament de les anteriors “La gran onada calenta” i “Un bòfia massa viu”. Un policia ell tot sol contra el crim. Aquest cop, de fet ja ni és policia. El van declarar culpable d’assassinat, fer fora del cos i empresonar cinc anys. Acabada la condemna, anirà a per els que li han arrabassat aquests anys de vida, i alguna cosa fins hi to més important.
És un home descomunal. Una màquina de repartir bufes. El fet de que ja no sigui policia el permetrà obrar al límit. Encegat, això farà també que rebin justos per pecadors. Danys col·laterals. Ah!... i cuida un gatet extraviat.
Un altre cas de venjança, de gàngsters i de policies venuts. Com les altres, ben escita, opino. I entretinguda.
