The episode starts with Ash and co. in exiting a building, probably a Pokemon Center.
Ash is excited for the next gym and Serena lets her Pokemon out.
Bonnie tells Clemont something before heading into a forest.
When Bonnie walks through the forest, she comes across three children.
Bonnie says something that scares the children a bit.
Ken is the bot with the blue shirt, Joe is the bot with the green shirt and Hina is the girl.
The three children are the Lapras Defence Corps, who are trying to heal an injured Lapras.
Hina picks up Dedenne and rubs cheeks with it, but ends up getting electrocuted.
She falls down on the ground afterwards.
All four children hear a sound in the distance and then they go to a rocky coast.
In the nearby water, there the Lapras is.
The Lapras Defence Corps take off the clothes that are covering their swimming wear.
Then they jump in the water, before Bonnie does the same thing.
The kids swim over to Lapras and remember when they met the injured Lapras.
Ken and Joe are hiding behind a rock and Bonnie is sitting on a rock nearby with Dedenne.
Hina is near Bonnie and then the three Lapras Defence Corps kids are annoyed at Bonnie for some reason.
All four kids are in a cave and talk to eachother and then they hold up something in the air.
They are also shouting something, probably their promise to help Lapras.
The kids hear some voices shouting for Bonnie and it is Ash, Serena and Clemont.
The two groups are now together, with Lapras and Ash uses his Pokedex on Lapras.
Clemont seems to be patting the Lapras.
The Lapras Defece Force kids (LDF) have another flashback.
In the flashback, the kids are in a town (Probably Lumiose) and they are with an Eevee.
Some lady sees the kids playing with the Eevee and I think they take it away from them.
Back in the present, Team Rocket are starving and they have on croissant in front of them.
Inkay comes out of its Pokeball and ends up eating it.
Dare Da? Lapras.
Nurse Joy has taken a look at Lapras and I think she has healed it back to health.
Ken, Joe and Hina are happy that the Lapras is now healthy.
Team Rocket are spying on the Lapras and they make a noise, which Lapras hears.
Lapras cries out and Ash and co. wonder why.
The group then plans to bring Lapras back to the ocean.
Serena pulls out her map to check where they need to take Lapras, I think.
The group then follows Lapras along to a dead end.
There are a bunch of rocks blocking their path.
Ash decides to bring out Froakie and Hawlucha.
Then Clemont brings out Chespin and Luxio and Serena brings out Fennekin.
All of the Pokemon attack the rocks and end up destroying them.
Then continue to lead Lapras back to the ocean.
Team Rocket block Lapras's path with their Magikarp submarine.
Jessie brings out her Pumpkaboo to attack Ash and co.
Ash and co. then notice that James is standing on a nearby small fishing plank.
James lifts up his hat that he used as a disguise, to reveal his face and Inkay is with James.
Lapras and the four kids go with Lapras, as Lapras heads for the ocean.
Team Rocket continue to attack Lapras.
There are some more Lapras nearby that are probably waiting for the lost Lapras.
Lapras used Hydro Pump or some sort of Water move.
Eventually Team Rocket blasts off and Lapras reunites with the other Lapras in the ocean.
The next day, Ash and co. leave a Pokemon Center, I think and then start running.
To be continued.
