***SPOILERS*** Practically unknown and forgotten little gem staring David Janssen as LA policeman Sgt. Tom Valens a cop who's been trying to get his nerve back since he came back on duty from an almost fatal gunshot wound.

Staking out the Seacape Apartment Complex one foggy evening for an on the loose serial murder Tom and his partner Sgt. Ed Mussco, Keenan Wynn,see this man sneaking along the complex swimming pool. Valens confronting the man and telling him to halt has him pulls a gun out of his jacket and is shot dead by the the undercover policeman.

Checking out his wallet the dead man turned out to be the respected Dr. James Ruston, Donald Curtis,a pillar of the community a philanthropist and champion of the poor and downtrodden in the L.A Mexican community and former Man of the Year of San Roserio to who's people he's considered to be a saint. Not finding Dr. Ruston's gun that Tom says he pulled on him has Sgt. Tom Valens suspended from the police force and set to be tried for manslaughter in Dr. Ruston's death.

The movie goes through a number of side stories about Dr. Ruston and the people who knew him including Mrs. Alice Willows, Lillian Gish, who Dr.Ruston was seeing the evening that he was shot and killed. Tom trying to get to the bottom of Dr. Ruston's strange actions that night comes across in number of contradicting facts about about Dr. Ruston that has to do mostly with his trips to Baja Mexico to help the poor there every Wendsday and then his seeing Mrs. Willows, making weekly night house calls to her, the next evening on a Thusrday?

Mrs Willows seems to have a advanced case of Alzheimer's and can't help Tom in his trying to find the reasons for Dr. Ruston's visits to her besides her diabetic condition, which didn't need his immediate attention. There's also the fact that Dr. Ruston was the person who got the old and senile Mrs. Willows the apartment at the Seacape Complex; was the man that much of a saint or were there far more cynical reasons behind his actions?

With his incitement imminent Sgt. Valens needs to find evidence to prove his innocence, by first finding Dr.Ruston's missing gun, before he's locked up behind bars. It dawns on Sgt. Valens that there's a connection to Dr. Ruston's trips to Baja that lead to his strange actions of him getting shot and killed but what exactly is it? There's also the fact that Dr. Ruston almost broke and bankrupt three years ago is now independently wealthy with no evidence of him having falling into any large inheritance so just where did Dr, Ruston's money come from? his many philanthropic ventures to and from Baja Mexico?

Things get even worse for Sgt, Valens when after seeing Dr. Ruston's secretary Liz Thayler, Stepanie Powers, she's later found murdered and he's the prime, and only, suspect in her death. There's also an attempt to murder Valens at his home by spiking his bottle of butter milk, medication for is ulcers because of him getting shot,and then turning on the gas range while he was out cold.

With Sgt. Valens and Mrs Willows next door neighbor, and his friend and licensed pilot, Walt Cody, George Grizzaed, planing to fly down to Baja to uncover Dr. Ruston's secret activities Valens suddenly changes his mind after Liz's murder realizing that the evidence to clear himself is not in Baja Mexico but right here in L.A County.

That night with an all out city and state police search for him, in both Dr. Ruston & Liz Thayers deaths, Sgt. Tom Valens goes to the spooky and deserted L.A's "Eternal Rest" Pet Cemetery to dig up the evidence that not only will clear his name, form pending manslaughter and murder charges, but his consciences as well.

During a 1966 break from filming The Fugitive TV series, David Janssen joined with producer-director Seymour "Buzz" Kulik and screenwriter Mann Rubin to film Warning Shot. The film finds Janssen in familiar territory as a man wrongly accused and having literally no recourse but to defend himself, and his performance as LAPD Sgt. Tom Valens can be seen as another alter-ego of Richard Kimble. The presence of Fugitive alum such as Carroll O'Conner and Ed Begley Sr. adds to the familiarity for Fugitive fans.

Jerry Goldsmith composes a strikingly strong score for the film, from the mildly bombastic opening theme through its more mournful renditions throughout the movie.

Janssen's performance as Richard Kimble made The Fugitive a television clasic, and here he imbues Sgt. Tom Valens with identical sympathy. Valens, on a stakeout for a prowler, encounters a doctor, James Rustin, who pulls a gun on Valens and is shot. The gun flies out of Rustin's hand, and is lost.

Because the gun cannot be found, Valens is suspended, and faces even greater trouble because Dr. Rustin has earned a striking popularity with neighbors of his for his medical efforts, both in LA and in his frequent flights to Baja. When Valens digs into Rustin's past, he finds some discrepencies with the doctor's image, but it all blows up in Valens' face in the death of a model Rustin was having an affair with.

Nonetheless, despite persistent pleas from his friends to admit to guilt, Valens pushes his investigation of Dr. Rustin, and he hits paydirt when he finds a curious truth about one of Rustin's elderly neighbors (and her dog), and when someone tries to kill him and then Dr. Rustin's nurse is found dead, leading to a confrontation between Valens and his ex-partner.

Janssen shines in this film, but gets superb help from his supporting cast, including George Grizzard as a playboy pilot who is always missing out on the action - or so he says.
