There is no picture attached, so I'm just going to assume that after Peter receives the message, he takes it very seriously.
He follows the instructions to board the boat on Tuesday at midnight to intercept the spy who is helping blindside the King of France.
He rides his steed until he is so exhausted, he falls off and passes out in the middle of the road.
A carriage finds him and takes him to the inn where they are staying.
Peter wakes up refreshed, with a beautiful woman leaning over him, stroking his forehead.
He asks where he is and where his clothes are. After asking questions of her own, the woman finds out Peter is on a quest and tries to kill him. Peter finds out then and there that the woman is the spy he was sent to intercept.
He tries to overpower her, but her guards come in and tie him up. Peter is forced to go with them to the boat at midnight.
The guards find that the ship captain is dead with the rest of the crew and Peter's friends save him and capture the spy.
France is saved.
the end
(If you can name the movie this plot is from I'll love you forever)
