Frank Connor je policist iz San Francisca. Ima hudo bolnega sina, ki nujno potrebuje presaditev kostnega mozga, sicer bo umrl. Izkaže se, da je Peter McCabe primeren darovalec zanj. A McCabe je psihopatski morilec, ki v strogo zavarovanem zaporu preživlja dosmrtno kazen. Ko ga pripeljejo v bolnišnico, kjer naj bi opravili poseg, McCabe izkoristi priložnost in pobegne. Frank mu je takoj na sledi in ujeti ga mora živega, če hoče sinu rešiti življenje.
San Francisco police officer Frank Connor is in a frantic search for a compatible bone marrow donor for his gravely ill son. There's only one catch: the potential donor is convicted multiple murderer Peter McCabe who sees a trip to the hospital as the perfect opportunity to get what he wants most: freedom. With McCabe's escape, the entire hospital becomes a battleground and Connor must pursue and, ironically, protect the deadly fugitive who is his son's only hope for survival.
