On ready reserve received four hour call out at 5:30 pm from crew Scheduler who told me I had a ZZZ and a ZZZ1 layover.  I assumed it was a three day.  Only to find when I pulled it up it was a two day with a continuous duty over night on the first night.  I called to inquire how this was legal after being available all day; getting into ZZZ after midnight with a 5 hour layover?  We of course were provided a hotel room; but by the time we deplaned; waited for in our rooms to basically try to lay down for a quick nap in our uniforms.  We were all so fatigued starting out that late at night knowing that we would not be able to sleep until we got to ZZZ the next day landing 10 hours later.  In the event of an emergency it is completely unsafe to function with no rest.  It is unrealistic to expect a reserve to perform such an trip safely with 4 hours notice.
