1
00:00:02,076 --> 00:00:05,551
Season four follows the fourth book, Cibola Burn.

2
00:00:05,571 --> 00:00:06,601
The gates are open,

3
00:00:06,621 --> 00:00:08,451
and more than a thousand new worlds

4
00:00:08,471 --> 00:00:10,151
wait on the other side.

5
00:00:10,171 --> 00:00:11,401
The first fight is over

6
00:00:11,421 --> 00:00:13,526
a planet called Ilus.

7
00:00:13,546 --> 00:00:16,376
Refugees from Ganymede got there first.

8
00:00:16,396 --> 00:00:17,651
Then a company arrives

9
00:00:17,671 --> 00:00:19,876
with a United Nations charter that says

10
00:00:19,896 --> 00:00:21,676
the planet is theirs.

11
00:00:21,696 --> 00:00:23,966
Three stories: the peacemaker,

12
00:00:23,986 --> 00:00:26,191
the settlers, and the scientist.

13
00:00:26,211 --> 00:00:27,486
Spoilers ahead!

14
00:00:28,238 --> 00:00:30,193
Story one: Holden.

15
00:00:30,213 --> 00:00:33,118
Avasarala and Fred Johnson send the Rocinante

16
00:00:33,138 --> 00:00:35,243
to Ilus to keep the peace.

17
00:00:35,263 --> 00:00:37,518
Holden has a passenger nobody else can

18
00:00:37,538 --> 00:00:39,418
see: the ghost of Miller,

19
00:00:39,438 --> 00:00:41,543
built by the protomolecule.

20
00:00:41,563 --> 00:00:42,918
Miller wants to know what killed

21
00:00:42,938 --> 00:00:44,693
the aliens who made it.

22
00:00:44,713 --> 00:00:45,643
On the ground,

23
00:00:45,663 --> 00:00:48,253
Holden finds the company's security chief,

24
00:00:48,273 --> 00:00:50,518
Murtry, a hard man who treats

25
00:00:50,538 --> 00:00:53,521
the settlers as trespassers and is ready to shoot.

26
00:00:54,107 --> 00:00:55,637
When disaster strikes,

27
00:00:55,657 --> 00:00:57,912
Murtry sees a war he can win.

28
00:00:57,932 --> 00:01:00,527
He hunts down settlers he calls terrorists,

29
00:01:00,547 --> 00:01:02,202
and kills some of them.

30
00:01:02,222 --> 00:01:04,352
Then a strange infection spreads through

31
00:01:04,372 --> 00:01:06,677
the rain and blinds almost everyone

32
00:01:06,697 --> 00:01:07,952
on the planet.

33
00:01:07,972 --> 00:01:09,552
Holden can still see,

34
00:01:09,572 --> 00:01:12,627
because his cancer medicine protects his eyes.

35
00:01:12,647 --> 00:01:15,177
He leads the survivors through the dark,

36
00:01:15,197 --> 00:01:16,102
and in the end,

37
00:01:16,122 --> 00:01:18,480
Murtry is locked up to face trial.

38
00:01:19,240 --> 00:01:21,465
Story two: Basia Merton.

39
00:01:21,485 --> 00:01:23,165
He's a welder who fled Ganymede

40
00:01:23,185 --> 00:01:23,990
with his family,

41
00:01:24,010 --> 00:01:26,440
and he lost his son Katoa there.

42
00:01:26,460 --> 00:01:30,290
On Ilus, the settlers mine lithium to survive.

43
00:01:30,310 --> 00:01:31,740
To keep the company away,

44
00:01:31,760 --> 00:01:33,515
Basia helps plant bombs under

45
00:01:33,535 --> 00:01:35,210
its landing pad.

46
00:01:35,310 --> 00:01:37,440
But the shuttle comes down early.

47
00:01:37,460 --> 00:01:40,410
It crashes, the company's governor is killed,

48
00:01:40,430 --> 00:01:41,685
and Basia has to live

49
00:01:41,705 --> 00:01:42,818
with what he did.

50
00:01:43,574 --> 00:01:45,379
As the planet turns deadly,

51
00:01:45,399 --> 00:01:47,954
Basia warns Holden about the settlers' plans

52
00:01:47,974 --> 00:01:50,379
and chooses to help instead of hide.

53
00:01:50,399 --> 00:01:52,554
Alex, who has made his own mistakes

54
00:01:52,574 --> 00:01:53,324
as a father,

55
00:01:53,344 --> 00:01:54,949
becomes his friend.

56
00:01:54,969 --> 00:01:58,049
Basia survives the storm and the blindness,

57
00:01:58,069 --> 00:02:00,824
and Holden chooses not to prosecute him.

58
00:02:00,844 --> 00:02:02,774
He gets back to his family.

59
00:02:02,794 --> 00:02:04,999
Settlers and company workers start building

60
00:02:05,019 --> 00:02:06,299
a new town,

61
00:02:06,319 --> 00:02:07,778
side by side.

62
00:02:08,428 --> 00:02:10,544
Story three: Elvi Okoye,

63
00:02:10,564 --> 00:02:12,493
a company scientist who survived

64
00:02:12,513 --> 00:02:14,063
the shuttle crash.

65
00:02:14,173 --> 00:02:16,178
Ilus is full of alien ruins,

66
00:02:16,198 --> 00:02:17,648
and they're waking up.

67
00:02:17,748 --> 00:02:19,828
An ancient power plant explodes,

68
00:02:19,848 --> 00:02:22,398
and a giant storm sweeps the planet.

69
00:02:22,493 --> 00:02:24,423
An alien defense system shuts off

70
00:02:24,443 --> 00:02:27,023
the reactors on every ship in orbit.

71
00:02:27,043 --> 00:02:29,048
Their orbits start to sink.

72
00:02:29,068 --> 00:02:30,873
Naomi turns a rail gun

73
00:02:30,893 --> 00:02:32,273
into an engine to save

74
00:02:32,293 --> 00:02:33,323
a falling ship,

75
00:02:33,343 --> 00:02:34,531
with help from Havelock,

76
00:02:34,551 --> 00:02:37,348
a company officer who changes sides.

77
00:02:38,082 --> 00:02:40,022
Miller has found something strange:

78
00:02:40,042 --> 00:02:42,962
a dead spot in the alien network.

79
00:02:42,982 --> 00:02:44,412
Elvi and Holden head deep

80
00:02:44,432 --> 00:02:45,672
into the ruins,

81
00:02:45,692 --> 00:02:47,372
and Elvi carries Miller's core

82
00:02:47,392 --> 00:02:49,497
into the dead spot herself.

83
00:02:49,517 --> 00:02:52,832
Every alien machine on Ilus shuts down,

84
00:02:52,852 --> 00:02:54,157
and the ships in orbit get

85
00:02:54,177 --> 00:02:55,582
their power back.

86
00:02:55,602 --> 00:02:57,357
Elvi also finds the cause

87
00:02:57,377 --> 00:02:58,832
of the blindness.

88
00:02:58,852 --> 00:03:00,157
The scientist who wanted

89
00:03:00,177 --> 00:03:02,677
to be left alone saves everyone.

90
00:03:03,414 --> 00:03:05,119
Season four ends with proof

91
00:03:05,139 --> 00:03:07,469
that people can live on new worlds.

92
00:03:07,489 --> 00:03:10,089
Elvi and Basia stay to help rebuild.

93
00:03:10,164 --> 00:03:11,119
But back home,

94
00:03:11,139 --> 00:03:13,419
the gates are changing everything.

95
00:03:13,439 --> 00:03:16,184
Why spend centuries terraforming Mars when there

96
00:03:16,204 --> 00:03:18,519
are ready-made planets next door?

97
00:03:18,539 --> 00:03:19,544
And the Belters,

98
00:03:19,564 --> 00:03:21,489
who did the hardest work in space,

99
00:03:21,509 --> 00:03:23,289
are being left behind.

100
00:03:23,309 --> 00:03:25,564
Someone is about to make them listen.

101
00:03:25,584 --> 00:03:28,458
Next up: where Fred and Amos came from.
