A U.S. government agent is killed on the slopes of Vail, Colorado, while investigating a rumor that someone will kidnap Carl Hansworth, a special aide to the President. Fearing that the identity of all federal agents has been compromised, the government turns to outside help- the Angels- to provide protection.

During a check of the guests at Hansworth's hotel, the Angels encounter Vincenti Donatelli and his son, Paolo, both members of an Italian Radical group called the Patriots for a Free Society. Their suspicions of the group are confirmed when Sabrina is kidnapped, and offered an exchange for the voluntary surrender of Hansworth.

While tracking an embezzler, Kelly is badly wounded and taken to the hospital. Bosley and the other Angels keep a vigil for Kelly, and reminisce about her adventures with the group.
