Summarily the queen has delivered her orders.
A plot summary, my wiki.vassal, of La Traviata:

Act I
The courtesan Violetta, recovering from an illness, throws a lavish party.
There, her current lover and would-be one vie for the favors of her affection.
By night’s end, Alfredo the usurper has Violetta singing to herself differently.

Act II
After the lovers live together in the country, they naturally fall apart.
Then they get back together. Then they fall even further apart. Etc.
All this time, in the country and the city, they keep up their singing.

Act III
Almost together, the lovers keep singing in the grim face of death.
Alfredo survives a duel with the Baron, the wicked former lover.
Lovers reunite. Violetta regains her strength to sing. She expires.
