This is the second short featuring Sam Sheepdog and Ralph Wolf. The title is a play on the phrase "Ship ahoy!".
By the time Sam sits on the edge of his cliff to watch over the sheep, Ralph is already attempting to carry a sheep away. Sam casually pushes a rock over the ledge, which falls on Ralph's head. In a stupor, Ralph places the sheep on the ground and lets it go just before he falls unconscious and grows a large lump on his head.
Ralph next attempts to drop a large boulder on Sam, but a tree branch catches the boulder and propels it upwards again as it crushes Ralph.
Ralph's next attempt is to pole vault over Sam to get a sheep. Sam casually grabs the pole, lowers it over the edge until Ralph is eye level with Sam, and punches him in the face.
Next, Ralph attempts to sneak into the field by surrounding himself with a cloud of smoke from an Acme smoke bomb. Sam heads him off at the pass and drops a stick of dynamite in his smoke cloud. After the explosion, Ralph stumbles back in a cloud of black smoke. With his lack of vision and coordination, he accidentally falls off a cliff.
In Ralph's fifth attempt, he uses an Acme disguise. The box is labelled "Acme artificial rock. Have fun. Be popular. Be a rock!" Ralph attempts to sneak past Sam with the rock disguise, but Sam hits the fake rock with a sledge hammer. Ralph breaks apart into a number of small rocks which all move back into Ralph's cave.
Ralph's next attempt is to dive off a cliff while tied to a very large helium balloon and carrying a fishing rod to snag a sheep. As he casts his rod, he unwittingly snags his balloon with his fish hook and rips the balloon, sending him flying into the horizon.
Ralph then attempts to tunnel under the field, as he did in Don't Give Up the Sheep. As he reaches up through the holes, he feels what appears to be four sheep legs strapped on to a large drum of TNT. Believing this to be a sheep, he pulls it into his tunnel. After the explosion, he places the riven drum back where it was sitting and politely refills his tunnel.
In Ralph's eighth attempt he swims through a stream with a peddle-powered submarine to catch a sheep which is taking a drink of water. As he swims, Sam holds a sign in front of his periscope which reads "DETOUR". After following the arrow on the sign, Ralph falls off a waterfall.
Ralph next attempts to propel Sam off his perch by placing an improvised teeter totter under Sam and dropping a rock on it from a large height. Unfortunately for Ralph, Sam is propelled straight upward toward Ralph's cliff, upon where he grabs Ralph by the neck and begins punching him in the face.
Finally, the punch clock whistle blows and Sam and Ralph change shifts with their replacements. Their replacements stand in the same position Sam and Ralph were standing in before the whistle blew and the replacement dog begins punching the replacement wolf in the face.
This is also the only episode where you see Ralph's replacement. Ralph's replacement refers to Ralph as "George", and Ralph refers to him as "Sam".
On ABC, the end of the short where Sam and Fred take turns punching Ralph in the face was shortened. Also cut was the scene where Sam drops a stick of dynamite into Ralph's smoke cloud, making it appear as though Ralph's smoke cloud exploded on its own.
