Cootch learns that the victim was a member of a secret society known as the Fenians, a diehard Gaelic group seeking freedom for Ireland. Delving deeper into the terrorists' underworld, Cootch uncovers a looming attack on his beloved Beantown, beginning with the planned assassination of a visiting British dignitary, Winston Churchill. With the help of his Boston cop brother, Cootch embarks on a fateful mission destined for bomb, bullets and blood.
