The Isle of Dogs at the turn of the century was a close-knit community. Here in Trinidad Street, the lives and loves of four families tangle and interweave...When Tom Johnson, a union leader at the docks is sacked and set upon, his daughter Ellen has to leave school and her dreams of an office job. But she can still dream of Harry Turner...But Harry, a young lighterman struggling to keep his battered family together, is bewitched by silver-tongued beauty Siobhan O'Donoghue. And Siobhan, ambitious for greater things, will use any weapon to repay the people of Trinidad Street for her disappointments. And Gerry Billingham, if he doesn't go a deal too far in pursuit of a retail empire, will be there to pick up the pieces ...Through good times and bad, from the coronation of Edward VII to the dock strike, some will find what they are looking for - and Ellen and Harry realise too late what they have lost.
