The ball is tipped
and there you are
you're running for your life
you're a shooting star
And all the years
no one knows
just how hard you worked
but now it shows...
(in) ONE SHINING MOMENT, IT'S ALL ON THE LINE

The next play means the next game.
No, it means the next thing that happens in the game you are playing.
In this case, "(at this moment) it's all on the line", means that what happens next will have a big effect on the outcome of the game.
As MikeNY says, it's also probably a metaphor for those moments in life when so much depends on what you do next. A moment when something important in your life is "on the line".

I think it's a betting reference. You put your money "on the line" at a casino and lose it if you lose the wager.
The others are right that it is being used to talk about the importance of a play in a game.
