European finance ministers are pinning their hopes on a meeting this weekend to break the impasse between Greece and its creditors, just days before a deadline to avoid Greece's default.
After more than 24 hours of intense negotiations in Brussels, officials say both sides are even more immovable than when they began.
Greece's future in the euro - and perhaps even the eurozone - hangs in the balance.
It's been the third emergency meeting in a week and there's still no deal.
International Monetary Fund Managing Director Christine Lagarde says fatigue is starting to set in.
"We need to do some more work to examine their proposal, to see how it can be reconciled, if there are good measures we can include. And all I can say is that the three institutions have been absolutely on the same page over the last few weeks, and up until now, and we will continue to work that way. We really want to show flexibility and we want it to be as growth-friendly as possible and we want it to work. But it has to be balanced."
Five months of negotiations culminated in a final offer from Greece's creditors, the so-called troika: the European Commission, the IMF and European Central Bank.
But Greece is not happy with the plan.
Penions and taxes remain the sticking points.
The creditors think Greece can save money by reducing pension payments, but Greece says it has already made cuts in that area.
The troika also wants a 23 per cent tax on restaurant bills.
But as the tourist season begins, the Greek government has offered instead a plan to tax successful businesses and the wealthy.
Greek Prime Minister Alexis Tsipras says he is optimistic a deal can be struck when both sides meet on Saturday.
"What's going on? You don't know? So I think that European history is full of disagreements, negotiations, and then compromises. So after the comprehensive Greek proposals, I am confident that we will reach the compromises that will help eurozone and Greece to overcome the crisis."
Eurogroup Chairman, Jeroen Dijsselbloem says there is still time for an agreement.
"The door is still open for the Greek side to come with new proposals or to accept what is on the table. But we are, on a number of issues, quite far apart. So it is going to be difficult."
But German finance minister Wolfgang Schäuble says he is not so certain.
"We have not made progress. It is time for Greece to decide on its responsibilities and then to tell its people what is on the table. Responsibility for the decision is exclusively up to Greece. They have so far moved backwards. Therefore, in my view, they have nothing to put forward."
The government faces pressure from many of the 18 other eurozone nations, who do not want Greece to be granted debt relief unless it agrees to austerity measures.
Back in Greece, anti-capitalist protesters in Athens say the Greek government should not give up on its push for debt relief.
Antarsya member Michalis Rizos has accused the government of succumbing to blackmail from international creditors.
"We need to break away immediately from the European Union, the I-M-F and the so-called creditors, who we consider to be loan sharks and not lenders, because from the developments so far, we see that they will stop at nothing. They keep asking for more sacrifices from the Greek people and the Greek workers."
Time is running out for Greece to make a debt repayment of $2.2-billion to the I-M-F on Tuesday.
Failure to do so could trigger a run on banks, and could force Greece's exit from the Eurozone - with possible repercussions for the rest of Europe and the world economy.
Amid the uncertainty, Greek account-holders took more than $2.17-billion a day out of the banks at the end of last week - more than one per cent of the total.
