Synopsis for "The League of the Unicorn!"
Steve Rogers and Bucky Barnes spot an Asian man being chased by a gang calling themselves the League of Unicorns — an Asian gang that wear unicorn horns on their heads. Changing into Captain America and Bucky, the two heroes fight off the man's attackers, forcing their leader King Unicorn Zang to order their retreat. The dying Asian man tells Captain America and Bucky that the League of Unicorns seeks to destabilize relations between the United States and China and says that in order to do so they plan on assassinating the visiting Prince Tsaihoon and Princess Yana, and dies.
As the royals are travelling by train to Lee City, they are targeted as their train rolls over a rail bridge over the Black River. The League of Unicorns attempt to raise the bridge to cause the train to fall into the water below. However, Captain America and Bucky interfere with the plan forcing the rails back into their proper position and forcing the Unicorns to flee once more. Boarding the train, Captain America and Bucky tell the royals about the threat on their lives, and they agree to let Cap and Bucky act as their protection while they visit Lee City. Just then, a rock is thrown through the window of their passenger car containing a note from King Unicorn Zang warning Captain America and Bucky that protecting the royals will lead to their death.
Arriving in Lee City, the royals, Captain America and Bucky are introduced to the mayor and Burton J. Hargrave, the owner of the railway they were riding on. As they are loaded up in cars to head to city hall, the one that is supposed to carry the princess is taken over by members of the Legion. In attempting to fight them off, Captain America and Bucky are overpowered and the League manages to kidnap both the princess and Bucky before escaping.
Taken to their mansion hideout, the captives are taken to King Unicorn Zang who sends another letter to Prince Tsaihoon. This one demands that he come to the mansion alone to spare the life of his wife. Captain America decides to disguises himself as Tsaihoon and go in his place. His disguise fools Zang and the others enough for Cap to attack them. During the fight Cap kicks out their lantern plunging the room in darkness. As the Unicorns struggle to find light, they find that Captain America has seemingly fled. However, Cap is hiding in the rafters of the building and then follows the League of Unicorns to their true hideout, an Asian dry cleaning establishment in Chinatown. There he fights his way through the guards and falls through a trapdoor that leads him to a series of underground tunnels.
Meanwhile, Zang gloats his victory to Princess Yana and Bucky, telling them that he intends to assassinate Tsaihoon so that foreigners will no longer meddle in the East and ancient rulers may take over once again. Bucky frees himself from his bonds and attacks the Unicorns alone until Captain America arrives. The duo fight off the gathered Unicorns but Zang escapes with Yana. As they are untying Yana, Burton Hargrave appears telling them that he was searching for the League himself and knew about these old abandoned subway tunnels and thought to search them independently. Sending Bucky to get the police, Cap and Hargrave enter the tunnels to search for Zang, but Hargrave disappears.
Spotting Zang, Captain America chases after him but is slowed down when he is attacked by a massive warrior employed by the Unicorns. Zang meanwhile has Yana tied up once more and threatens to kill her with a strong acid. Captain America arrives shortly and smashes the vials of Zang's acid before he can use them. Zang gets the upper hand when he tosses a grenade that causes a cave in that covers Cap, but the hero pulls himself out and begins fighting Zang again. Just as other members of the League arrive to stop Cap, Bucky arrives with the police and rounds them up. With the fight over, Captain America reveals Zang to be none other Burton Hargrave, who hopes to snatch up power for himself in the east by destabilizing China through the death of the royals.

Synopsis for "The Lighthouse of Horror"
The Last Chance Lighthouse is a supposedly haunted lighthouse that helps guide ships away from a dangerous reef during the night hours. A group of thugs led by a man named the Looter have set up shop nearby, and using a remote device to snuff out the lighthouse light, they cause ships to crack up on the reef so they can loot them, leaving the ships to sink and the crews to drown.
The next day, Sgt. Duffy is reaming out Steve Rogers once more for his poor performance when Bucky enters the room with a letter from Betty Ross. Reading the letter, they learn that Betty is coming back from her vacation aboard a boat coming in through Washington. Bucky is excited because it gives them the opportunity to check out the Last Chance Lighthouse, whose haunted legend interests Bucky very much. When they hear a radio report about the sinking and looting of a ship that was filled with gold, they decide to go into action as Captain America and Bucky to make sure that nothing happens to Betty's boat.
That night as the ship pulls ashore, Betty is spending time with fellow passenger Mr. Phillips. Phillips is about to propose marriage to her but misses the chance when Betty is suddenly distracted by the lighthouse light going out. Shortly thereafter the ship gets caught on the reef. Meanwhile Captain America and Bucky, also noticing the light going out, go to investigate but find that the door to the lighthouse has been put out. Spotting that Betty's ship has been caught on the reef and a group of men are boarding the ship, the two heroes go to their rescue. Aboard the ship, Betty has lost track of Mr. Phillips when she is grabbed by one of the pirates. Cap and Bucky attempt to fight their way through but Cap is knocked out by a blow to the back of the head and Bucky is taken prisoner.
Coming around, Cap rushes back to the lighthouse and forces his way in. He is attacked by the lighthouse keeper who throws a stool at him before disappearing in a hidden elevator. Finding the secret passage to the elevator, Captain America catches up to the keeper and stop him. When the keeper (named Leems) denies any shipwrecks he flees from the Captain again and bars the door to prevent Cap from following him. Cap decides to give up chasing the keeper and focus on finding Bucky and Betty.
In a secret chamber within the lighthouse, the Looter has Bucky and Betty as his hostages. He tells Betty that he does not intend to harm her but that he must kill Bucky. While outside, Captain America finds the secret entrance to the room, fights off the guard on duty and makes his way inside. Cap fights off the pirates, but the Looter manages to escape. Freeing Betty and Bucky, the trio follow after the Looter who traps them in a room that he begins flooding with water. Hearing another boat getting caught on the reefs, the trio double back and Cap and Bucky fight off another attempt by the pirates to loot. While the two heroes are distracted, the Looter reappears and captures Betty again.
With the pirates rounded up, Captain America and Bucky go after the Looter, deciding to question Lems again. They learn that Lems is really blind, and that he had the help of an assistant that promised not to tell his employers so he could keep his job. Cap and Bucky realize that the Looter had been manipulating the blind man for his own ends. Realizing how he has been duped, Lems shows them the way to a secret room that the Looter has been using. There Cap catches the Looter off guard and knocks him out with a single punch. Realizing he was wearing a mask, Cap removes it revealing him to be none other than Mr. Phillips.
