Scientist Bruce Banner scours the planet for an antidote to the unbridled force of rage within him: the Hulk. But when the military masterminds who dream of exploiting his powers force him back to civilization, he finds himself coming face to face with a new, deadly foe.

Police Chief Jesse Stone, who was suspended by the Paradise, Mass. Town Council, begins moonlighting for his friend, State Homicide Commander Healy, by investigating a series of murders in Boston, leaving Rose and Suitcase to handle a crime spree in Paradise on their own. Jesse pours his energy into his work in an effort to push away his twin demons: booze and women. When his investigation leads to notorious mob boss Gino Fish, Jesse's pursuit becomes hazardous.

Police Chief Jesse Stone's relationship with his ex-wife worsens, and he fears he's relapsing into alcoholism. To get his mind off his problems, Jesse begins working on the unsolved murder of a bank teller shot during a robbery. Also, his investigation of an alleged rape draws him into conflict with the town council — which hopes to preserve Paradise's reputation as an ideal seaside resort.

Jesse Stone and Captain Healy are shot during an unauthorized stake-out in Boston. Meanwhile, a cryptic letter sent from Paradise leads the mother of a kidnapped child to Stone. Though her son was declared dead, she hopes he will reopen the case.
