Hillary Clinton and Donald Trump will take to the stage again on Sunday evening for the latest presidential debate.
An estimated 100 million people tuned in to the first debate two weeks ago, and given the developments seen in the race this week, interest is expected to be huge again when the two candidates face-off.
Here's what you need to know about the debate:
When does it start?
The debate will start at 8 p.m. Central and ends around 9:30 p.m., with six segments of debate lasting 15 minutes each.
How can I watch?
Take your pick. It will be shown on every major network (CBS, ABC, FOX, NBC, CNN, MSNBC) as well as public channels like C-SPAN and PBS.
You can watch online too, with YouTube and Twitter providing live streams of proceedings.
What's the format?
Unlike the first debate, which saw candidates field questions selected by moderator and NBC anchor Lester Holt, Sunday's debate will be done in the "Town Hall" style.
As such, half of the questions will be posed by citizens in the audience, with the other half posed by moderators Martha Raddatz, of ABC's "This Week," and CNN anchor Anderson Cooper.
After each question, candidates will have two minutes to respond and an extra minute will be given for discussion.
U.S. Presidential Election News reports the audience members will be uncommitted voters selected by the Gallup Organization.
It will be held at Washington University, St. Louis, MO.
What will be discussed?
Again, unlike the first debate in which the topics were known before hand, the town meeting style means the subjects for discussion are likely to be broader.
But events of the past week are likely to feature.
In the past few days, Donald Trump has found himself under pressure like never before, after recordings of a lewd conversation he had in 2005 has prompted scores of Republican leaders across the country to desert him.
CNN reports that Trump, who has since apologized, could bring up Bill Clinton's extramartial affairs while president to attack his opponent should he be called to answer for his comments about women.
Meanwhile, Hillary Clinton could also be set for questions after Wikileaks released thousands of hacked emails from the campaign, which included partial transcripts of private speeches she gave to Wall St. bankers.
These emails allege Clinton called for "open trade and open borders" as well as admitting she was "kind of far removed" from her middle class upbringing because of the success she and her husband have enjoyed since he was president, CBS News notes.
CBS also suggests that with the Town Hall format, citizens could also bring up other controversial issues that have dogged the candidates, such as Trump's tax returns and Clinton's emails.
In between all that, they might actually get to talk about their policies.
