I'm not certain, but let see what can be figured out.
Questions:
Could a better photo be taken? Even the scale is hard to judge
Are fruit on the same plant as the leaves in the shot? I'm thinking perhaps not.
Was this photo taken in England or elsewhere? It looks like a garden setting.
Is it known if the the plant is annual or perennial?
The berries themselves remind me of White Bryony (Bryonia dioica) but usually such fruit is more clustered and on shorter pedicels.
Perhaps the fruit of a type of Asian May-apple (such as Sinopodophyllum hexandrum), but again fruit shape and placement seem off.
I am curious. If your friend could take some more photos, it would be appreciated.
