Collision is a five-part television drama miniseries, which debuted on ITV & UTV in November 2009. In the same month, it was also on PBS as a series in two parts. It tells the story of a group of strangers whose lives intertwine following a devastating car crash. The crash opens a number of startling revelations as stories of everything from government cover-ups and smuggling, to embezzlement and murder start to unravel.
The series is open-ended, with a number of unresolved issues; moreover, the story is ostensibly resolved in a metafictional manner with a flashback to an incident in the service station and the swatting of a wasp, which precipitates the initial crash, thus allowing the characters to carry on on their journeys. The wasp as a motif and theme is frequently in evidence throughout the series.
The original British broadcast of Collision was edited from the original 5 hours down to three and a half hours. The American broadcast on PBS's Masterpiece Contemporary, the Australian broadcast on ABC1 and the Region 1 DVD release all featured the shortened version. In Australia, Foxtel and Austar's W Channel aired Collision in its original format of five 45-minute episodes, Tuesday, 15 March 2011.
