This film dramatizes the actions of a greedy an unscrupulous fisherman and provides a caution for those who would behave in the same way. A cigar-chewing businessman (Fishog) sits in his office and contemplates his approaching fishing trip; a calendar shows the date is June 16th. Fishog examines his rod and tackle-box which sit in the corner of his office. Holding a lure in his hand he calls in his secretary and tells her to wire Sprague that he'll be arriving as planned. Fishog makes a telephone call and then, leaning back in his chair, looks wistfully at the fishing lure in his hand.~On the road to Pete Sprague's, Fishog stops to ask Joe Turner, the fire ranger, for directions, offering him a cigar for the favour. Joe obliges, but cautions Fishog about fishing too early, showing him a poster of the "Ontario Game and Fishery Laws," which reveal that bass season opens July 1st. Fishog discards the poster and drives away leaving Joe concerned that "A man who has no consideration for fish would have less for trees." Joe throws away Fishog's cigars and makes a note in his notebook. Later, on the way to his cabin, Joe runs into his friend Frank Drew, the game warden. Leaning out his car window Joe tells Frank about Fishog, the fourth fisherman this spring to inquire about Pete Sprague's. When Joe reaches his cabin, he calls a look-out tower to check in. The tower-man says, "All O.K." and the viewer is shown the vista of lakes and forest from the tower.~At Pete Sprague's Fishing Camp, "A fish hog's paradise where the law means less than nothing," four men admire an impressive catch of fish. When a car horn honks, the men hide their fish, fearing it is the game warden. But it is only Fishog. He parks his car and declares his goal of beating last years record of 48 bass in a single day. Fishog greets the other fishermen and shows off his tackle box and lures. Frank Drew arrives and posts the game and fishing laws, reminding Pete that its spawning season for bass, and too early to fish for them. Taking Pete aside, Frank warns him that at the current rate there will soon be no fish and Pete will be out of business. Pete warns him to mind his own business and leave him alone. Instead of searching Petes ice-house for fish, Frank decides to leave and win Pete over some other way. After putting up another poster, Frank leaves.~The next morning finds Fishog ready to beat his old record. He meets with much success, since nesting bass strike at anything. After a busy morning Fishog stops for lunch. The forest protection tower-man watches as Fishog leaves a fire smouldering and returns to his fishing boat. With a phone call, Joe is on his way to take care of the fire. Joe interrupts Fishog's fishing and directs him to return and put out his fire completely.~The fire extinguished, Joe goes to pay Pete Sprague a visit, and finds him burying fish. Confronted, Pete asks what crime there is if there are plenty more fish. Joe explains that the numbers can't last because each fish caught leaves over 15,000 "little ones"; defenseless, they are easy prey and the number of older bass are diminished. If there are no more bass, Joe argues, there will be no tourists for Pete. Joe appeals to Pete to help Frank uphold the fishing laws. Joe then takes Pete to see Egbert, his pet nesting bass. Joe and Pete find Egbert in a sheltered cove. Pete is impressed with the bass' concern for its 15,000 eggs.~Meanwhile, the tower-man keeps watch of Fishog's greedy work. When Fishog nears Egbert's cove, the tower-man calls to warn Joe. With Pete by his side, Joe runs to Egbert's aid, but arrives too late; starved from protecting his young, the bass is easy prey to "Fishog's murderous bait." Joe stares down at Egbert's abandoned eggs. In the fishing boat, Egbert twitches and Fishog announces his new record: fifty bass in a single day. Joe and Pete run back to Joe's cabin where the forest warden phones Frank, and tells him about Egbert. As Pete leaves the cabin, he tells Joe that he and Frank can depend on him.~Having reached his goal, Fishog speeds back to Pete Sprague's where he loads the fish onto his car and drives away. When he stops for gas, Frank sees his crate of fish and confronts him. Fishog, chewing a cigar, gives one to Frank and offers him fifty dollars to let him go. Frank refuses and takes Fishog, along with his fish and gear to the local police magistrate. Twenty-five minutes later Fishog is on his way, "minus his fish, rod, marvelous tackle box and two hundred dollars of a fine." Frank and the gas station attendant smile as Fishog drives home from his expensive trip. Frank telephones Joe to tell him, "Egbert is avenged." Elsewhere, a sign is being painted warning guides that breaking the law will not be tolerated by Pete Sprague. <30mn 26s>
