When their carpentry and plumbing operation takes them to a boarding school, Danny meets Angie, an 18-year-old girl.

The film was shot on location in North Wales and at Goldhawk Studios, Shepherd's Bush, London, England.

But while the frustrations of the beginning are perceptively handled, there is a scattering of over-explicit scenes towards the end ... and the happy conclusion comes at a glib rush.

Jules Bricken directs from his own screenplay, and if his film ultimately fails to establish itself very clearly, this seems more a fault of the writing than of anything else.

Indeed, after the finely characterised conflict of the opening sequences – with Frank Finlay as a heavy father more dependent on emotional blackmail than physical threat, and Len Jones' Danny a study in puzzled acquiescence – the relationship between father and son gradually slips away through a lack of writing: something more needs to be said about the motives and feelings of both sides in the final confrontation, and about the uneasiness of the ostensibly happy balance with which the film ends.
