Plot
In 1807 China, the pirate Madam Ching raids a village and, using a gem, unwittingly releases the Sea Devil Marsissus from a stone statue. Marsissus kills Ying Wai, the young Ying Ki's father, who was tasked with keeping Marsissus contained. The Doctor, Yaz, and Dan arrive to confront Marsissus and investigate the village. Ying Ki and Dan take the gem, split off, and swim to Ching's ship to take revenge. Ching reveals she is after the treasure of the legendary sailor Ji-Hun (who disappeared searching for the Flor de la Mar treasure) because she needs it to pay the ransom for her kidnapped crew. The Sea Devils unleash a leviathan, the Huasen, on Ching's ship.

The Doctor and Yaz take the TARDIS back 274 years and witness a Sea Devil betraying Ji-Hun aboard the latter's ship. Returning to 1807, they try to find the shipwreck to no avail. The Huasen takes the TARDIS to the Sea Devils’ undersea lair. The Sea Devils seek the gem, the Keystone, to execute their plan. Pretending they have it, the Doctor and Yaz use it as leverage to board Ji-Hun's ship, which has been retrofitted with alien technology. They are shown Ji-Hun, who has been kept in stasis. He reveals he tricked the Sea Devils in their deal. Marsissus calls the Doctor's bluff, claiming the Huasen has located the Keystone.

Ji-Hun, the Doctor, and Yaz board Ching's ship. Ji-Hun finds out Ying Ki is the descendant of his most trusted crew member Lei Bao and reveals he gave the Keystone to Lei, who escaped his ship. Marsissus seizes the Keystone from Ying Ki just as the Doctor realises the Sea Devils plan to use it to flood Earth.

The protagonists fight the Sea Devils aboard Ching's ship. The Doctor tampers with the technology on Ji-Hun's ship, but destroying it requires two cables to be held together. The Doctor volunteers to stay back while the others escape, but Ji-Hun offers to sacrifice himself instead.

Madam Ching announces she has recovered enough treasure to pay the ransom and will make Ying Ki a member of her crew. The Doctor takes Yaz and Dan ashore. Dan leaves a message for his love interest Diane and is surprised when she calls him back. The Doctor, who had acknowledged Yaz's feelings for her on Ji-Hun's ship, solemnly expresses her wish that she could spend more time with Yaz.

Benji Wilson, writing in The Daily Telegraph, said that his kids thought the Sea Devils were "cute" which undermined the perceived scariness of the episode. However, he praised the "nascent queer relationship between the Doctor and Yaz" commenting that the interplay between the two characters was "genuinely affecting".

Awarding it three stars out of five, Martin Belam of The Guardian said the episode "promised a swashbuckling Easter special, and it partially delivered", but he felt that the scenes between the Doctor and Yaz towards the end "didn't necessarily ring true". The i's Stephen Kelly gave the episode one star and criticized a thinly written supporting cast, as well as "a frenzied plot". Kelly opined that the Doctor and Yaz's affection was one of the one of the only redeeming qualities of the episode.
