"Dragon Ball Super" episode 4 is entitled "Mission Dragonballs: Pilaf Gang's Big Plan."
In "Dragon Ball Super" episode 4, Beerus and Whis are heading to King Kai's planet. Goku is still training there as well. The next scene showed Bulma's birthday party and bingo tournament.
Similar to the "Battle of Gods" film, the first prize for the contest are all seven Dragon Balls, which were hidden beneath the cruise ship. Trunks and Goten manage to find all the Dragon Balls.
Emperor Pilaf, Mai and Shu make their first appearance in "Dragon Ball Super" episode 4. They were stuck on a little island as Pilaf hunted for fish while the other two tried to look for some treasure. Pilaf discovered that the Dragon Balls were nearby using the Dragon Radar.
The trio managed to get close to the cruise ship and was able to board with Trunks and Goten's help. Although it was implied that Pilaf and his gang would be able to find something big in "Dragon Ball Super" episode 4, they did not find the Dragon Balls yet.
A brief scene of Vegeta's training was depicted with Bulma on the phone getting angry at him for not being able to attend her birthday party. "Dragon Ball Super" episode 4 implied that he is not going to the party but he will eventually appear if the story is based on "Battle of Gods."
The last part of "Dragon Ball Super" episode 4 showed King Kai ushering Goku inside his house. He was paranoid because Beerus and Whis were already heading to his planet. He does not want the pair to know about Goku.
The episode ended with Beerus and Whis standing in front of King Kai. The title for "Dragon Ball Super" episode 5 has been revealed. It is entitled "Goku vs God of Destruction Beerus" and seems to be an action-packed part of the series with Goku going head-to-head with Beerus.
