Logline ideas for my opening sequence

• A mystery call leaves everyone unnerved, whilst the town start to realize what secrets are being hidden
• An ageing man confronts a mysterious girl from his past who reappears after years of keeping quiet however will what she has to stay ruin everything.
• When a stranger arrives in town things start to go wrong, its up a local teenager to stop them before its too late.

My favourite log line from the ones i have designed is 'A mystery call leaves everyone unnerved, whilst the town start to realize what secrets are being hidden'  this would work as my opening sequence as already it starts to demonstrate a sense of mystery which fits in with genre of my opening sequence which is to be thriller.This sense of mystery can be transferred on to my opening sequence by using quick shots and obtrusive editing which helps create this suspense and tension. As its quite a vague log line it will enable me to experiment more with my opening sequence and not have to stick to a specific specification meaning its more easier to produce. The other log lines i feel will be quite difficult to create in to an opening sequence for example i may not be able to gain access to the location in which it requires to be set.
