Overcrowding
The thousands of families trapped in overcrowded housing in Britain report huge strains on their relationships.
According to Shelter's research, one in ten overcrowded households has teenagers of the opposite sex sleeping in the same room. In Trapped, we see how awkward it is for Molly when she gets her period in the room she shares with her brother Jack.
And adults often have no privacy either, as Trapped shows when the parents have to share a bed with the younger children to give Molly some space. This creates friction and destroys relationships.
The irony is that the family in Trapped wouldn't even be officially classed as overcrowded – as babies aren't counted and a young child like Jack or Lucy would only count as half a person.
Impact on health, education and life chances
People living in overcrowded, damp or dilapidated housing lose out on many different levels.
The effects on the family's mental and physical health in Trapped are true to life. Research by Shelter has found that children in bad housing are twice as likely to be sick as their contemporaries, and their mothers are twice as likely to get depressed.
Living in a stressed environment, with no room to study or think, children in bad housing are also twice as likely to leave school without any GCSEs.

Temporary accomodation
Because of the shortage of permanent housing, many families are forced to make regular shifts between b&bs, hostels and short term housing.
Unsurprisingly, the children miss up to a quarter of the schooling, as travelling to old schools becomes difficult and new places have to be found. This disruption affects academic performance and often leads to bullying, as Jack experiences in the film.
The instability of temporary accommodation also makes it hard to hold down a job, as the father finds in Trapped.
Unaffordable homes
There are 1.6 million households are waiting for social housing in England as there are not enough homes to go around. But privately renting a home - let alone buying - is now out of reach for many people. So, as Trapped shows, people are renting homes that are far too small for their needs.
When families do become homeless through no fault of their own (and as we saw in the film, eviction can happen for something as minor as complaining about the damp), the shortage of council homes can cause disastrous consequences.
Take action
One in seven children are trapped in bad housing. Britain needs more homes now.
