barrier seem to be one of those series that have be lose in the mist of time . after it transmission in the early 80 and one repeat and it since sunk without trace . this be a cry shame . i originally watch this when it be transmit in the southern tv region on sunday afternoon and be classic tea time view . although i do not remember a great deal about the program and a few thing stick in my mind . most notable be the unforgettable title . the mournful flute music accompany the attempted escape across an east european border and the subsequent car crash ( and that scene have leave me with an abide love of fintail mercedes model a they use a merc 200 ) . although it wasn not obvious at the start and the solution to the series mystery be in these title . the plot about a young music student try to unravel what really happen when he discover he be adopt have lot of twist and turn but barrier be a surprisingly adult child drama . benedict taylor be excellent a billy and it be a shame he do not do a lot more . this be a quality drama and well overdue for a dvd release and i hope i will get the chance to re acquaint myself with it in the future . a fond memory from my childhood .
