Tomato plant gone mad

My daughter only has a very tiny garden so she normally grows tomatoes, cucumbers and other oddments in pots by the fence. However this year she was not as organised as usual and a tomato plant grew which she assumes is seeded from last years crop. It had so many branches and leaves that you could not see the tomatoes so she decided to crop the branches AND look what she found .........didn't count them but there are masses. Whether they will ripen is doubtful but if not I am happy to help her make green tomato chutney !!
