No biographical details are currently known.
She only has 13 credits on IMDb, and does not seem to appear in 2 of those, leaving her with 11 credits spread out over a 20-year period. With such a small known filmography it would seem highly likely that there could be undocumented roles to be found.

1967 - Las cicatrices .... Curo's mother (credited)
- Luis Candelas, el ladrón de Madrid (1947) IMDb as Manuela
- Cabo de Hornos (1956) IMDb with no role. She is not credited and I didn't find her. There are only a couple of female roles in the film so I'm sure if she did appear she would have been found.
- Dones d'aigua (1997 TV series) Ep.3: "La sequoia". IMDb with no role. It seemed unlikely, though not impossible, that Angela would turn up in a small role in a Catalan language TV episode 30 years after her previous role. There is an Angela Pla credited, however there are no women in the episode who look to be an appropriate age, so it presumably must belong to someone else.
