Frank Cannon was a detective with the Los Angeles police department. However, he resigned after the deaths of his wife and son in a car accident and later became a private detective. The series begins at the point where Cannon is just beginning this new career (the pilot film picks up after Cannon has just spent 2 1/2 months overseas on an investigation). The cause of death of Cannon's wife and child was not clear through the first four seasons of the show. However, the first episode of the fifth and final season revolves around Cannon's investigation of the deaths, and he finally finds out the reason they were killed.
The noticeably overweight Frank Cannon had expensive tastes, especially in food and cars. (His primary vehicle was a silver '71 Lincoln Continental Mark III.) Cannon's investigations were mostly for clients in the Southern California area, although on occasion he was called in for investigations much farther away (e.g., New Mexico in the pilot).
Cannon occasionally would get hurt (shot or beaten) and knocked unconscious. He carried a gun for self-defense, usually a snub-nosed .38 Special revolver. He was known to subdue suspects with karate chops, judo holds, and occasionally he would thrust and knock down adversaries with his huge abdomen.
In the first two seasons Cannon was a pipe smoker. In the third season, the pipe was seen occasionally; it was subsequently dropped altogether.
