Summarized this for a friend of mine:
Texans wants to ban abortion clinics. Democrat woman talks for 12 hours straight to prevent vote. Republicans want to break rules and stop her from talking. Other democrats protest. They get ignored. This happens:

Crowd continues cheering for 30mins. Vote may or may not have happened before midnight, nobody knows.
To get technical - the vote was to put up stringent but bullshit restrictions on abortion clinics that would've caused all but 5 clinics in Texas to have shut down.
So in effect, a backdoor ban on abortion.
Majority of texans against it - Democratic senator stood up and told them ahead of time that this was going to be fillibustered if they insisted on including it in the bill.
They do, and they enforce stringent requirements on the fillibustering process (no sitting, no leaning, keep on subject).
Senator gets up and proceeds to fillibuster under stringent conditions for 10+ hours before republicans finagle some bullshit to say that she was out of line. Other democratic senators getup and attempt to fillibuster that ruling in order to help them ride out the time. They do, all while the republican side pulls more and more bullshit, upto and including flat out ignoring the rules that they created.
Crowd starts cheering for epic burn, using it as a pretense to help ride out the clock for the democrats. Mass confusion ensues and Republicans attempt to push through the vote irrespective of uncertainty and lack of clarity during crowd interruption.
