Following THE TOUGH ONES, this fourth collaboration between director Umberto Lenzi and star Tomas Milian introduced Milian's iconic character of "Monnezza." When a scheming convict (Milian) is sprung from prison by a hard-nosed cop (Claudio Cassinelli), they'll team up to hunt down Monnezza's former crime partner (Henry Silva) who's kidnapped a critically ill child.
