Ep 4. Single Strand

In the fourth episode of the first season of Helix, entitled "Single Strand," tensions rise as the team continues to investigate the outbreak on the Arctic base. With limited resources and time running out, the scientists must work quickly to find a cure for the deadly virus before it spreads beyond control.

As the episode opens, we see Alan and Julia searching through the contaminated living quarters for any signs of the virus. Meanwhile, Sarah and Peter are busy studying the DNA samples they've obtained from the infected patients. They discover that the virus has a highly unusual genetic makeup, consisting of a single strand of RNA - something that shouldn't be possible in nature.

As the team struggles to make sense of this new information, new obstacles arise. A member of the base security team becomes infected and the others must race to contain the outbreak. Meanwhile, tensions between Alan and Julia reach a boiling point as they clash over the best course of action.

As the situation becomes increasingly dire, the scientists turn to Sergio Balleseros for help. Though he's been largely untrustworthy thus far, Balleseros may hold the key to saving everyone on the base.

As the episode comes to a close, the situation is still far from resolved. The team is still working tirelessly to find a cure, but it seems that every discovery only raises more questions. With the virus continuing to mutate at an alarming rate, it's unclear whether they'll be able to find a solution before it's too late.

Overall, "Single Strand" is a tense and thrilling episode that raises the stakes for our protagonists. As the virus continues to spread and mutate, the clock is ticking for the scientists to find a cure. With its complex plot and intense action, it's clear that Helix is a show that keeps viewers on the edge of their seats.
