An aspiring actress living in 1946 New York, Angie will befriend Peggy Carter (Hayley Atwell) as she herself seeks to find her place in the post-war world.
Here's what Marvel's Head of Television Jeph Loeb had to say in a statement.
"Marvel's Agent Carter opens up an exciting world of new characters for us. Lyndsy brings a warmth and humanity to Angie, who'll be the friend Peggy needs if she's to survive the dangers that lie ahead."
