Serangoon Road
Episode 9
S1 E9:
When Sam goes out on a limb for an ex-WW2 Australian soldier accused of murder, no-one understands why he's so sure the man is innocent - least of all Macca, who was half in love with/half mentoring the murdered girl. Either an innocent man is going to gaol for life, or Sam has made a very big mistake about his hero and friend.
