Mati (Antonio Akeel) has lived with his foster Mother, Rosie (Rosie Cavaliero) and brother George (Leon Harrop), who has Down's syndrome, since he was seven years old. When Mati turns 18, in the midst of his birthday celebrations, he receives a letter which will change his life. His application for the right to remain in the UK has been denied and he will be deported back to Afghanistan. Devastated and terrified at the prospect of leaving the country, Mati goes on the run. When Mati goes missing and immigration enforcement officers turn up at the door Rosie and George begin to panic, leading George to run away from home in search of his brother. With both of her sons missing Rosie is distraught, but she is determined to find the boys and find a resolution to this seemingly impossible situation.
