Film a sheep running under tree on old homestead (6,2,3,4)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

PLANE (tree), TOFT (old homestead), then anagram [running] of A SHEEP. This was another answer that gave me major problems as it was one of my last clues solved and its long absence deprived me of checkers to help with four words in the troublesome SE corner. I realised when writing the blog that I had failed to account for T OF T but fortunately the SOED came to my assistance with this entry: toft –  a homestead, the site of a house and its outbuildings. Freq. in toft and croft, an entire holding, consisting of the homestead and attached plot of arable land. OE. I never ever ‘eard of it!
