Most of the characters are important but if I had to pick a main character I'd say Selene is the main character. Although, in Rise of the Lycans the main character is probably a tie between Sonja and Lucien.
French: voici ma main English: here is my hand
"In my handbag" in French is written "Dans mon sac à main". If you just want to say "In my bag" then the "à main" part isn't needed.
