Single dad David Holtz needs a new heart. And if he doesn’t find one soon, his six-year-old daughter, Chloey, will end up in a foster home. Turns out, the biotech company he used to work for, Gentax Corporation, has a brand new genetically engineered heart waiting for him at its secret research facility, somewhere in the jungle of southeast Mexico. But there’s a catch. The new heart was harvested from a wolf. And the stem cell infusion he must undergo to prevent rejection–well, that’s from a wolf as well.
