Out of the Unknown: Time in Advance

"Time in Advance" is the fifth episode of season one of the British science fiction television series Out of the Unknown. It was directed by Paddy Russell and written by Mike Watts and first aired on BBC2 on November 8th, 1965. In this episode, hobbiest Henry Wilkes cultivates rare tropical plants with an attention to detail which is, perhaps, closer to an obsession. The length to which he goes to propagate and nurture new hybrids alarms his wife.
